Can Huawei’s visual intelligence drive surpass Tesla? Pure vision confronts the dispute between cost and performance

Huawei HarmonyOS Ecological Spring Communication Conference was successfully held on the afternoon of April 11th. This conference focused on the new products of Zhijie S7 and MateBook. Zhijie S7, the first car built by Huawei and Chery based on HarmonyOS Zhixing model, was unveiled in November last year.

The intellectual community "returned to the furnace" after half a year, which attracted attention. Huawei chose to re-release it because of its Huawei visual intelligent driving system, which is the first time Huawei has launched a visual driving solution without lidar.

At the press conference, Yu Chengdong said that Huawei’s visual smart driver equipped with Zhijie S7 has surpassed Tesla, which is known as the "originator of vision", in real vehicle performance, showing strong confidence in its own scheme.

How does Huawei’s visual intelligence drive compete with Tesla’s visual intelligence drive on the premise of abandoning lidar? What kind of sensor does its technical strength come from? Huawei revealed the answer at the meeting.

Huawei officially released the first visual intelligent driving product-Huawei ADS Basic Edition. According to Yu Chengdong, the scheme can realize NCA intelligent driving navigation assistance on national expressways and urban expressways, including intelligent driving on and off ramps, coping with complex scenes such as road construction and cone-bucket diversion, and has certain ability to change lanes and avoid obstacles independently.

HUAWEI ADS basic edition is not equipped with laser radar, but realizes environmental perception through three millimeter-wave radars, 10 visual perception high-definition cameras and 12 ultrasonic radars, so as to build a visual intelligent driving scheme without laser radar.

At the press conference, Huawei ADS Basic Edition pointed directly at Tesla EAP(Enhanced Auto Pilot Enhanced Driver Assistance). Huawei claims that the comparative test results show that the coverage rate of Huawei’s visual intelligent driving is as high as 99.5%, the pass rate of ramp is 96%, and there is no degradation in the whole process. At the same time, it has the functions of intelligent speed regulation and identification of water horse cones. In contrast, the coverage rate of Tesla equipped with EAP is only 79%, the on-ramp pass rate is 68.75%, and it has been degraded 14 times, and it is impossible to identify obstacles of the opposite sex.

In terms of intelligent parking, Huawei’s visual intelligent driving has completely surpassed Tesla, which lacks support for different shapes, oblique rows and custom parking spaces.

As an optional function, Tesla EAP includes four functions: automatic lane change assistance, automatic navigation and driving assistance, intelligent calling and automatic parking, which need to be purchased at an extra cost. Tesla’s self-driving products are divided into three grades: BAP, EAP and FSD, of which BAP is the basic version and EAP is the enhanced assisted driving, and the two are free and charge $6,000 respectively. FSD is Tesla’s highest-level self-driving product, which has the functions of navigation-assisted driving, automatic lane change, automatic parking, intelligent calling, traffic signal recognition, and automatic turning of urban roads.

Zhijie S7 has launched five models, with the price range of 249,800 yuan to 349,800 yuan. Among the new models, the Ultra version uses a 100kWh battery pack, while the Max and Max+ versions have a price reduction of 20,000 yuan compared with the initial listing.

It is worth noting that Huawei Vision Smart Drive HUAWEI ADS Basic Edition is only installed in Zhijie S7 Pro rear drive long battery life version. In contrast, the version of Zhijie S7 Max with a price higher than 20,000 yuan is equipped with the same 192-line laser radar as that of Wenjie M9, with the longest detection distance of 250m, which is 20% higher than the industry average. Except for lidar, there is no difference in other configurations between the two models.

From this point of view, whether equipped with lidar has become the main difference between the basic version and the high-end version of Huawei’s ADS intelligent driving scheme, and the price difference between them is mainly reflected in this 192-line lidar.

What is the difference between Huawei Smart Drive with and without lidar? The former has enhanced its omni-directional anti-collision ability. After Zhijie S7 is equipped with laser radar, the effective range of forward active safety AEB is expanded to 4-150km/h, and the maximum braking speed is increased to 120 km/h; The effective range of lateral active safety is increased to 40-130km/h, and obstacles such as water horses can be actively identified.

The existence of lidar significantly improves the safety protection performance of vehicles, especially when dealing with emergencies such as "ghost probe". Previously, an owner of the M7 car in the border area encountered a "ghost probe" accident while driving at a speed of nearly 130km/h at high speed, and a pedestrian suddenly crossed the isolation belt and broke into the fast lane. Fortunately, Huawei’s intelligent driving system equipped with the M7 in Wenjie timely identified and took evasive measures to avoid the tragedy. This successful obstacle avoidance case is largely due to the lidar carried by the vehicle. Under extreme conditions, it is difficult to achieve such accurate perception only by visual sensors or human eyes.

In addition, the advanced version of HUAWEI ADS equipped with lidar has achieved wide coverage of roads in China, covering more than 40,000 towns and villages in China, including main roads, branch roads and even smaller roads. The third-party test data shows that the road coverage rate of the system has reached 99.56%. In contrast, the basic version of HUAWEI ADS-visual intelligent driving scheme is currently only applicable to NCA intelligent driving navigation assistance for national expressways and urban expressways.

Despite this, lidar is still recognized as the strongest sensor to achieve high-order assisted driving at this stage, even Huawei is no exception.

Why do some manufacturers choose to give up lidar? High cost is the main reason. Compared with the Zhijie S7Pro rear-drive long-life intelligent driving version, the Zhijie S7Max rear-drive long-life intelligent driving version is 20,000 yuan more expensive, mainly because of the addition of laser radar. Are consumers willing to pay for this?

In December, 2023, DJI Vehicle cooperated with Chery to launch the mass-produced model iCAR 03. This model adopts 7V pure vision sensor scheme, and the whole vehicle has no millimeter-wave radar or ultrasonic radar, making it the first automobile in China to realize high-order driving assistance function only by pure vision sensing hardware. With the help of pure visual sensor hardware, iCAR 03 also supports high-order assisted driving functions such as cross-layer memory parking, urban memory navigation and high-speed navigation.

The intelligent driving solution "Chengxing" launched by DJI Vehicle takes the inertial navigation stereo binocular sensor as the core sensing device, provides 7V and 9V pure vision sensor configurations, and supports extended multi-sensor such as lidar. This scheme can realize a variety of L2+ high-order intelligent driving functions with a computing power configuration as low as 32TOPS. Among them, the 7V sensor scheme includes an inertial navigation binocular vision sensor and five cameras, and the 9V sensor scheme adds two side-looking monocular cameras on this basis.

The hardware cost of DJI vehicle-mounted binocular vision intelligent driving scheme is extremely low. According to Shen Shaoshua, the person in charge of the vehicle in DJI, the hardware cost of the "Chengxing" platform can be reduced to less than 10,000 yuan, even reaching the level of 5,000 yuan, which is roughly equivalent to the price of a long-range lidar.

Both Chery’s cooperation with DJI Vehicle and Huawei’s cooperation have put forward a vision intelligent driving scheme without lidar version, which shows the active exploration and trade-off of domestic automobile manufacturers in the field of intelligent driving, and reveals how to introduce intelligent driving technology into a lower price range through trade-offs.

Although lidar is irreplaceable for its high-precision sensing ability, even Huawei acknowledges its watershed position between the basic version and the high-end version of HUAWEI ADS. However, with the intensification of competition in the automobile market, domestic automobile manufacturers are eager to introduce intelligent driving technology into a lower price range, and enterprises such as DJI and Huawei have achieved mass production of visual intelligent driving solutions that do not rely on lidar.

Therefore, reducing the cost of lidar has become a top priority.

On September 9th, CNMO noticed that a car blogger "ID- Hanchao" published a document saying that a company prohibited employees from buying LI. At the same time, the blogger exposed the announcement that a company prohibited employees from buying LI.

We can see that the information in the relevant announcement shows that Guangzhou Mike Industrial Co., Ltd. announced: "From today, the management of the company is forbidden to buy LI or commute to LI. According to the fifth point of the Code of Conduct in Chapter 2 of the Human Resources Management System, if the above behavior is found, it will be dismissed."

The company said that recently LI maliciously plagiarized the patent of our rear tent, and as the first company to put forward the concept of tram camping, it was being bullied by enterprises from LI in its most familiar industry. For example, some time ago, the ideal image quality and the ideal film pasting event. The company claims that LI is just an enterprise that deprives others of their ideals. As the bullied party, we should not support it, especially as the core personnel of the company.

At present, LI officials, the Ministry of Justice of LI and Li Xiang, CEO of LI, have not responded to this matter.

Not long ago, LI announced its market results in August 2023. The data shows that LI delivered a total of 34,914 new cars in that month, with a year-on-year increase of 663.8%, and the monthly delivery of three models of the ideal L series all exceeded 10,000. Since January 2023, the cumulative delivery volume in LI has reached 208,165 vehicles. Since the second quarter, LI has been the top-selling brand of high-end SUVs (including fuel vehicles and new energy) with a price of over 300,000 yuan in China for five consecutive months.

On June 24th, a Weibo by A Leng, the former anchor of Mo Mo, caused quite a stir in the live broadcast field. After a two-month hiatus, A Leng announced his return to his fans and will join DouYu.

heavely sound+Versatile and sweet girl with huge fans

As one of the most popular anchors of Momo, A Leng earned an annual income of 16 million yuan in 2016, and even created a miracle in the live broadcast industry that was rewarded with 30 million yuan in eight months. She is comparable to a first-line star and is a well-deserved sister of Momo. After graduating from a famous university, she also went to teach at the Confucius Institute in the United States in 2014. Not only did she get excellent grades, but A Leng also had an unusual talent in playing musical instruments. Both erhu and guitar won prizes in the competition.

A Leng looks sweet and has a voice that surprises people. In the colorful metropolis, she did not choose to go with the flow, refused to rely on her face value, and attracted a large number of diehard fans with her hard work and sincere singing. In the live broadcast world, A Leng is known as "online celebrity Clean Stream" and "talented female anchor". Compared with other female anchors in online celebrity, A Leng’s route is obviously different from theirs, with outstanding temperament, elegant clothes, cordial communication with fans, and singing one song after another. Just like this, A Leng’s live broadcast received a flood of praise, and more and more people began to pay attention to it.

High-quality platform holds hands with popular anchor DouYu and adds the top singer.

It is understood that A Leng’s first test of water in Betta attracted people to watch. On the day of registration, there were even more local tyrants who brushed gifts with black screens, which once made A Leng advance to the fourth place in the Betta anchor’s earnings weekly list before broadcasting. Interestingly, the area where A Leng lives in Betta is actually the League of Legends game area. A Leng’s strong joining will pose no small threat to Ti mo Feng, a betta sister in the League of Legends area, and Chen Yifa, a sweet singer.

It is understood that Ti mo Feng and Chen Yifa have 3.6 million and 2.3 million fans in Weibo, respectively, but there is still a certain distance between Alang’s 120,000 Weibo fans and the two major anchors. From this set of data, we can easily see that betta fish plays an important role in it, and the platform with wider coverage and stronger influence will greatly enhance the popularity of the anchor. I believe that the growth rate of the number of fans in Weibo will also become one of the concerns after Alang enters Betta.

The anchor camp shuffled and reorganizedBetting platform becomes the biggest winner

With the rapid development of the live broadcast industry, the participation of the whole people has become an indisputable fact. Under the hot situation of live broadcast, serious homogenization is rampant. If we want to fight our way out in the homogeneous industry, we must develop the platform competitiveness in an all-round way from multiple dimensions. For the live broadcast platform, it has become the core competitiveness to build a live broadcast platform by leading users and content anchors. The strong joining of Alun this time, its own strong flow will definitely bring a new round of "bombing" to Betta.

Ah Leng’s joining may not come as a surprise to the water lovers of fighting fish. Before Ah Leng, there was a girl named "Natto", a secondary oxygen girl, who was called bilibili’s first sister, who settled in fighting fish. With the birth of online celebrity’s economy, the competition of platforms for anchors is becoming increasingly fierce, but more and more anchors pay more attention to the platform quality and development prospects. Known by the industry as "the Whampoa Military Academy in the anchor field", after a group of anchors, such as Fu, Ti mo Feng and Yifa Chen, have grown into first-line online celebrity, the addition of A Leng has also started a new round of reshuffle and reorganization of the anchor camp in the industry, and Betta has gradually become the biggest winner in the live broadcast field with its strong anchor lineup and high-quality content. Today, with the rapid development of live broadcast platforms, more and more anchors will choose platforms with better user base and broader development prospects. It is not surprising that fighting fish will have more fresh blood injected.

It is reported that A Leng will start broadcasting in Betta at 21:00 on the evening of 27th, and we will wait and see what surprises she will bring us.

As we all know, the "second half" of the new energy vehicle market will be an intelligent competition. Near the end of the year, the domestic city NOA Kaicheng War intensified, and L3 test policy boots officially landed. On December 22nd, Changan Automobile announced that it had successfully obtained L3-level self-driving road test licenses for 17 expressways on November 17th, becoming the earliest enterprise to obtain such licenses at most in a single batch. How far is L3 automatic assisted driving?

"Made in Chongqing" car starts L3 road test.

A few days ago, China’s Ministry of Industry and Information Technology and other four ministries and commissions jointly issued the "Notice on Launching the Pilot Work of Intelligent Networked Vehicle Access and Road Access", which formally set specific requirements for L3/L4 autopilot access specifications and improved relevant rules. This means that China’s advanced autonomous driving has a clear policy support and responsibility definition.

The introduction of the new policy has opened the floodgate of mass production for the long-awaited smart car industry.

As of December 21st, 17 L3 self-driving vehicles of Changan Automobile have passed the 34-day road test. The L3 self-driving road test was carried out in Chongqing Inner Ring Expressway. The total length of this section is 74.1km, which is very mountainous, covering complex scenes such as construction, long slopes, continuous bends, bridges, tunnels, ramp entrances, etc. The traffic volume is large, with the maximum one-way cross-section traffic of 94,000 vehicles/day and the maximum peak traffic of 7,300 vehicles/hour. The whole section has normal traffic jams in the morning and evening peaks.

According to relevant sources of Changan Automobile, the traffic jam autopilot function of Changan Automobile has undergone a severe test in this road test.

At the same time, a number of "Chongqing-made" cars have also made great efforts in high-speed and urban NOA(Navigate On Autopilot). It is generally believed in the industry that the urban NOA is approaching L3, which is a crucial step from L2 to L3. In short, if you want to go from place A to place B, you only need to enter place B in the navigation, and you can hold the steering wheel to supervise how the vehicle waits for the traffic lights, changes lanes and gives way in the covered area.

On October 9th, Aouita Science and Technology announced that it would gradually open the NCA without map, and intensively carry out large-scale actual road test and user experience. As the core capability of Huawei’s advanced intelligent driving system ADS 2.0, Aouita has taken the lead in covering six cities, namely Beijing, Shanghai, Guangzhou, Chongqing, Shenzhen and Hangzhou, and the second batch of functions will cover another 16 core cities, with full coverage in China within this year.

The world under the banner of Celestial Automobile was the first to open the push of the city NOA. In July this year, the urban NCA function of the M5 Zhijia version was opened in five cities: Shanghai, Shenzhen, Guangzhou, Hangzhou and Chongqing. In December, the new M7 in Wenjie was equipped with HUAWEI ADS 2.0 advanced intelligent driving system, and the high-speed NCA intelligent driving navigation auxiliary function of the vehicle can be used nationwide without relying on high-precision maps.

Yu Chengdong, managing director of Huawei, CEO of terminal BG, and chairman of smart car solutions, mentioned in the latest order "Battle Report" published on social media in October that the selection rate of high-end packages of M7 five-seat Max version ADS was 70%, and that of six-seat Max version ADS was 68%.

The NOA timetable of car companies has been released one after another.

The competition for the city NOA is not limited to "Made in Chongqing".

On March 31st, 2023, Tucki fully promoted XNGP (Full Scene Assisted Driving) version 4.2.0, and all users of G9 MAX and P7i MAX can get this software version.

He Xiaopeng, CEO of Xpeng Motors, said, "We promise that the first city in China will drive Kaicheng &hellip in 25 cities by the end of November; …”

Subsequently, brands such as Ideal, Weilai and Zhiji have also announced the specific timetable of the city NOA. This means that it has completed 50% of the progress bar of the goal of opening a city in 50 cities.

In addition, Xpeng Motors has publicly stated that the Max version of Tucki G6 has an optional rate of over 80%, and the Max version of Tucki G9 has an optional rate of over 80%.

Recently, Li Xiang, CEO of LI, said on the social platform that the official version of NOA in December covers the national expressway and ring road and 100 cities, and the LCC function will be available worldwide.

Weilai also officially opened the test of NOA function in Shanghai in June.

On December 16th, Zhiji Automobile announced that its vehicles equipped with L3-level automatic driving function have officially obtained the high-speed highway automatic driving test license in Shanghai. At the same time, Zhiji is applying for the L3 announcement access pilot of the Ministry of Industry and Information Technology, and it is expected to be the first vehicle to enter the L3 autopilot access pilot.

On December 12, Gu Huinan, general manager of Guangzhou Automobile Ai ‘an, revealed: "Ai ‘an is applying for L3 autopilot together with Ruqi Travel, and strives to be the first to launch truly operational L4 autopilot in 2025."

On December 16th, Mercedes-Benz became one of the first enterprises to obtain the road test license of Beijing Conditional Autopilot (L3) Expressway. Two days ago, China’s first L3 test license was spent on BMW — — BMW announced that it has obtained the L3-class self-driving high-speed road test license in Shanghai.

Mercedes-Benz has made it clear that after Germany and the United States, it will promote L3-class autopilot system Drive Pilot in China market, and BMW Group plans to officially launch L3-class autopilot function in late 2023 or early 2024.

In August this year, Tesla CEO Musk revealed that Tesla is developing the last puzzle "Vehicle Control" of the FSD V12. The automatic driving system adopts an end-to-end solution. In November, Tesla has pushed the FSD V12 to employees.

The ideal NOA, NGP of Tucki or NCA of Huawei, under the influence of a dazzling array of technical terms, the "second half" of intelligent driving is really coming.

How far is L3 autopilot from us?

At the end of 2023, L2′ s driving function was gradually optimized. How far is L3 from us?

At the 5th China Automobile and Travel Future Forum, data show that at present, the penetration rate of intelligent driving above L2 will exceed 40%.

Many domestic progressive autonomous driving companies are also realizing data closed loop through mass production and high-order assisted driving scenes, and promoting the rapid maturity of autonomous driving technology; In addition, many key cities in China are also accelerating the construction of "smart cities", delineating pilot areas and promoting the coordinated construction of vehicles and roads.

It is understood that in terms of chips, NVIDIA leads the iteration of smart driving chips, Mobileye and TI technologies are mature, and the distance between domestic players Horizon and Black Sesame is gradually shortened. In terms of domain controllers and solutions, domestic players Desai Siwei, Jingwei Hengrun, Zongmu Technology, Zhixing Technology, etc. have all got on the bus on a large scale, and their technical maturity has been continuously improved. Laser radar: domestic suppliers such as Wo Sai, Tu Datong and Sagitar have a faster pace of mass production.

On November 26th, Hu Yang of Huaxi Securities pointed out that as of August, 2023, the country had opened more than 20,000 kilometers of test roads, and a large number of intelligent networked automobile products were developed, tested and verified. The opening of this pilot will help the intelligent networked vehicles to accelerate the technical level, and also accelerate the industrialization process of the smart car industry. L3/L4 smart driving will also accelerate its landing next year.

As a watershed between assisted driving and driverless driving, L3 autopilot needs not only technical support, but also coordinated support from policies, legislation, infrastructure and other aspects.

Last August, the first domestic regulation on intelligent networked vehicle management — — The Regulations of Shenzhen Special Economic Zone on the Management of Intelligent Networked Vehicles was officially implemented. This legislation is the first official management document in China to divide in detail important issues such as the rights and responsibilities of L3 and above automatic driving, and provides a policy basis for self-driving vehicles to legally go on the road. Although it is only exclusive to Shenzhen Special Economic Zone, its significance to the national intelligent networked automobile management legislation is self-evident.

The promulgation of the "Notice on Launching the Pilot Work of Intelligent Networked Vehicle Access and Road Access" has further accelerated the landing of high-level automatic driving.

In the current upgrade war of autonomous driving, mass production capacity is the "key" to cross L2 to L3. According to the above-mentioned Notice, the emphasis on mass production capacity again means that players without mass production capacity can’t even get "admission tickets".

Changan Automobile said that it will continue to pay close attention to the requirements of China regulations and, with the support of policies and regulations, will introduce L3-class autopilot function to the market at an appropriate time.

According to the data released by the Industrial Research Institute, it is estimated that the penetration rate of L3, a new car on sale, will reach 20% in 2023.

According to the agency’s forecast, in 2024, the urban NOA layout process will rapidly expand to 100 cities across the country, and the sales volume of NOA models will reach more than one million.

　　Netizen: The price is "outrageous"

　　"Some time ago, I unpacked the ticket blind box and got a ticket to Shanghai. I originally wanted to take advantage of ‘ May Day ’ Go to Disney on vacation, once ‘ Princess at large ’ However, the price of the hotel is really a bit discouraged. It is too close to live and it is a waste of time. " Ms. Zhang from Bayannaoer City, Inner Mongolia, told the client of Zhongxin Jingwei that she didn’t intend to travel too far, but just in time for the blind box activity of air tickets to be drawn to Shanghai, she temporarily decided on the travel itinerary. I didn’t expect hotels around Disney to be expensive and difficult to book. "It’s also my fault that I didn’t make plans early, so I have no choice but to consider shortening my itinerary and playing less for a few days."

　　Ms. Wu of Chongqing said to the client of Zhongxin Jingwei: "Express hotels are going to look like I can’t afford to live. It was originally a cheap and convenient plan to stay in the seven-day chain next to the scenic spot. When I searched the price, the big bed room would cost nearly 500 yuan a night."

　　On the social media platform, many netizens said that the price of hotels during this year’s "May 1" holiday rose significantly, and the price was "outrageous".

　　The south wind has not yet started-:Take Xiamen, where I live, for example, there are more than 200 hotels, and it will take 2,000 to get to May Day. It is understandable for hotels to raise prices appropriately during holidays. After all, business is not good at ordinary times, and holidays can make a wave, but this increase is too outrageous. Most of the money spent on accommodation when going out for a visit.

　　@ Shh, don’t say anything: it’s outrageous for more than one hundred to rise to seven or eight hundred, and it’s outrageous for small hotels to rise to two or three hundred.

　　@ Xiang kaixin: I have been planning the May Day trip for a long time, but it’s outrageous to be turned away by the hotel price of 3 times the scenic spot …

　　@ Learn good Xinyi sauce: During the "May Day" period, the price of this hotel is outrageous, and the usual room type of 180 is "May Day" 899.

　　According to Ctrip’s report data, during the May Day holiday in 2021, the order volume of Ctrip platform hotels increased by 43% compared with the same period in 2019. Many high-star hotels have been hard to find a room, and the price of hotel orders has risen, surpassing the average price in 2019. Judging from the hotel booking trend of the platform, during the "May 1" period, orders for 4 and 5 diamond high-star hotels accounted for over 50%, and more tourists were willing to buy high-quality travel services in high-star hotels.

　　Lan Xiang, dean of the Qunar Big Data Research Institute, believes that as early as this year’s Spring Festival, the "May 1" hotel reservations have increased significantly because a large number of suppressed travel needs have not been released. Lan Xiang said, "Although many tourists visited relatives and traveled during the just-concluded Qingming holiday, due to the length of the holiday, most of them will still choose ‘ May Day ’ Travel on holiday. "

　　Expert: it is not appropriate to interfere excessively with the price increase.

　　Zhang Yuhao, a lawyer of Beijing Weiheng Law Firm, said in an interview with Zhongxin Jingwei client that as the festival approaches, some homestay hotels balance the profit ratio of the whole year by appropriately raising prices, and such business practices may not constitute an illegal act of "driving up prices". "If the relevant operators join hands with neighboring operators in order to achieve violent profits within a certain period of time, and the price is greatly raised beyond a reasonable range; Or fabricate or disseminate false or related information, deliberately causing the price in this area to increase significantly beyond the reasonable range. If the above two situations occur, it may constitute ‘ Drive up prices ’ Illegal behavior. "

　　Zhou Mingxi, founder of Jingjian think tank, believes that the price increase of hotels or homestays is a market behavior that reflects the relationship between supply and demand. "In the period of oversupply, such as when the epidemic is serious, and in the traditional off-season of tourist cities, many five-star hotels sell for only three or four hundred yuan per night, which will definitely lose money from the perspective of operating costs. And the same room, in the peak season and holidays, the price of the room can reach several thousand yuan per night, the difference is multiplied. In the off-season, no one guarantees the income of the operators, and it is not appropriate to interfere excessively with the price increase in the peak season. "

　　"It should be noted that the market supervision department should focus on monitoring whether the hotel price is transparent, whether the room is hygienic and safe, whether it is suspected of exaggerating false propaganda, etc., to avoid the situation that the quality is not proportional to the price." Zhou Mingxi said.

　　　　　　 CCTV News:"The U.S. military regards quantum computing as a key weapon in the space war", which is the title of a report of the U.S. Space Network on July 15th. A few weeks ago, senior Pentagon officials began to discuss with scientists the future of quantum computing in the US military. What is quantum computing? Why is the United States waiting for it?

　　　　　　 On June 27th, 2018, the Committee on Science, Space and Technology of the U.S. House of Representatives passed the National quantum scheme Act, announcing that it will invest 1.3 billion U.S. dollars in 2019 -2023 to conduct state-level quantum technology research.

　　　　　　 On November 10th, 2017, IMB announced that it had successfully developed a quantum computer with 20 qubits. In addition, IBM has successfully developed the world’s first 50-bit qubit prototype.

　　　　　　 If the superpowers mastered nuclear technology in the 20th century, they would gain global hegemony. Then in the 21st century, a big country that has mastered quantum technology is called "quantum hegemony" by Preskill, a theoretical physicist at California Institute of Technology.

　　　　　　 In 1936, alan turing, the "father of computer science", submitted a paper entitled "On the Application of Digital Computing in Solving Difficult Problems" to the authoritative mathematical magazine in London. In the paper, an idealized computing model which can assist mathematical research was proposed, and it was later called Turing Machine. By using the permutation and combination of pure digital symbols 0 and 1, the connection with the physical world was established, and later this concept was applied to computers and became the core of modern computers.

turing

　　　　　　 Over the past 80 years, although computers have become smaller and faster, and the memory has become larger and larger, the basic core has remained unchanged. Until 2010, D-Wave, a company located in Vancouver, Canada, launched the world’s first commercial quantum computer, D-Wave One, which won the title of "revolution".

　　　　　　 Traditional computers use the smallest unit "bit" of binary data to process information. Each bit represents a binary digit, which can represent 0 or 1. These 0′ s and 1′ s, like switches, finally constitute calculation data for a simple operation. For example, to solve a maze, the traditional computer will try every possible route one at a time and finally find the right one. The method of quantum computing is completely different. Quantum computers use quantum bits and make use of the two principles of quantum superposition and quantum entanglement in quantum physics. Compared with electronic bits, quantum bits are fuzzy. That is, a thought experiment "Schrodinger’s cat" often mentioned in physics.

　　　　　　 To better understand how quantum computers work, let’s give an example from life. Imagine a library. We choose a book in the library, put a cross on one page of the book, and then close the book. Then we asked the traditional computer to find this fork in the book. Traditional computers will look at page by page, and they will soon find the page with the cross. But if the computer doesn’t know which book the fork is in, it must look at every page of every book, which will take a long time. If it is to find the fork on that page in all the millions of books in the world, it will take centuries for traditional computers and it is almost impossible to achieve it. But if there is a quantum computer, it is completely different. Because it can search all pages in all books at the same time, it can find this fork in a few seconds.

　　　　　　 The running technology on the traditional computer can skillfully find the rules buried in the massive information, but the quantum computer can give the answer when there is not enough information or too many solutions to find the rules.

　　　　　　 The huge difference between quantum computer and traditional computer in operation enables it to perform operations that traditional computers can’t do, and it can even solve some complex problems that the most advanced supercomputers can’t solve.

　　　　　　 Andrew Foresman and Langdon Downs founded the 1Qbit startup company six years ago, and convened the global "super brain" to build quantum software. This idea is being realized step by step. Foresman said that quantum computers may simulate the human world in the future.

　　　　　　 In the American sci-fi drama westworld, by copying and simulating people’s thinking, bionic people are created to continue their lives. More subtly, this kind of simulation and replication is not fixed, but slight defects may occur randomly. The origin and evolution of species are also due to unpredictable "defects" in the genetic process. This is also the key difference between machines and humans.

　　　　　　 With quantum technology, everything is possible.

　　　　　　 However, the conditions of quantum effect are very strict, and it is necessary to cool the quantum chip to near absolute zero with liquid helium, which is about equal to MINUS 273.15 degrees Celsius to run stably.

　　　　　　 In the future, the convenience brought by quantum computing technology will not only be reflected in life, but also contribute to the military.

　　　　　　 Canada’s Super Invisible Biotechnology Company claims to have developed a "quantum invisibility cloak", just like the invisibility cloak worn by Harry Potter, which can make the wearer "disappear" in people’s sight instantly. This kind of camouflage materials can bend the light, which can not only "cheat" the naked eye, but also be invisible under the detection of military night vision goggles, infrared rays and thermal imaging technology. Camouflage materials, a Canadian super stealth biotechnology company, was quickly recognized by the US military and gave the company a lot of financial support for subsequent research and development.

　　　　　　 At present, many countries have begun to study quantum computing technology.

　　　　　　 On August 16th, 2016, China successfully launched the "Mozi" quantum science experimental satellite. The US Space Network reported that the satellite adopted quantum secure communication technology and became an "invulnerable" satellite.

　　　　　　 Britain is planning a $400 million sensing and timing project based on quantum technology; A similar project in the EU is expected to invest $1 billion in 10 years; Canada, Australia and Israel also have considerable plans.

　　　　　　 In the early 1990s, Elizabeth Berman, a physics professor at Wichita State University, began to study the combination of quantum physics and artificial intelligence. But at that time, most people questioned this. Nowadays, artificial neural network and machine learning have become the most subversive technologies. They not only appear in tasks that humans are not good at, such as data mining, but also begin to appear in tasks that humans are good at, such as facial recognition. This means the personification of artificial intelligence. If quantum computing is used, it will completely solve all kinds of problems faced by artificial intelligence, and the future quantum war will really challenge the human brain.
