The ability to solve mathematical problems on a single property is equivalent to tens of billions of times the world's total ability.

Quantum computing is the development path of the future computing field. This is a disruptive technology that will inevitably replace traditional computers in the future. Progress in the field of quantum computing can strengthen the country in traditional computing. Achieve transcendence. On December 4, relevant media expressed my country’s achievements in quantum computing. The University of Science and Technology of China announced that it had successfully built a prototype of quantum computing, named Jiuzhang. It is the fastest quantum computer in the world and can be called another one of my country’s ?A powerful weapon?

How fast is Chapter Nine? It only takes 200 seconds to sample Gaussian Bose. Most people may not know the difficulty of sampling Gaussian Bose with a mathematical ball. If Fugaku supercomputer is used to solve it, it will take 600 million years. The speed of Jiuzhang is equivalent to 94.6 trillion times that of Fugaku, which means that in a single property The ability to solve mathematical problems is equivalent to tens of billions of times the world's total ability, and relevant papers have been published. Jiuzhang? Quantum is a computing prototype that is a collaboration between multiple centers. Its development requires overcoming three major problems: high-quality photon sources, phase locking and interference. The difficulty is very high. Regarding the output of high-quality photon sources, it is a great challenge to ensure that only a single photon is emitted each time, and it must be exactly the same. It is very difficult to turn on a light to emit an extraordinary amount of light, so that the bulb emits only a single light particle. One can imagine. The requirements for phase locking accuracy and other issues are also extremely demanding. It must be within 10^-9. At a distance of 100Km, the error cannot exceed the diameter of a hair.

The field of quantum computers is a competition between China and the United States. Google launched Suzuki, which has a single capability that is equivalent to more than 860 times that of traditional supercomputers, achieving a transcendence of tradition. Nowadays, the Jiuzhang computer developed by our country is about 10 billion times that of Suzuki. Our country is the second country to complete the leapfrog in the traditional sense. It is already in a leading position compared to Suzuki. Experts believe that in the future, in the quantum field The field will enter a new phase of development between China and the United States.
