What is it that makes the US military win the treasure! This technology makes everything possible？
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.

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.
