[Explanation] A research team composed of Academician Pan Jianwei of the Chinese Academy of Sciences, Professor Lu Chaoyang and other collaborators successfully constructed the "Nine Chapters" of 76 photon quantum computing prototypes.

According to the existing theory, in the “Gaussian Bose Sampling” task, the “Nine Chapters” task completed in one minute, the supercomputer needs 100 million years.

This marks the first time that China has achieved "quantum superiority."

  [Explanation] On December 4, the international academic journal "Science" published this result online.

The reviewers of "Science" evaluated the work as "a most advanced experiment" and "a major achievement".

  It can use big data, artificial intelligence, weather forecasting, financial analysis, drug design and many other aspects.

So because of this reason, quantum computing research has become the focus of this kind of competition among developed countries in Europe and America.

  [Explanation] According to reports, Pan Jianwei’s team has always been at the international leading level in optical quantum information processing. This time, it successfully constructed a Gaussian Bose sampling quantum computing prototype with 76 photons and 100 modes, which was named "Nine Chapters". It also has a special meaning.

  Why is it called Jiuzhang?

Everyone knows that a mathematics masterpiece in Chinese history is called "Nine Chapters Arithmetic", which tells us how to calculate. So we say that our computer is very fast in arithmetic, and it mainly has such a meaning in it.

  [Explanation] According to the current best classic algorithm, "Nine Chapters" can process Gaussian Bose sampling a trillion times faster than the world's number one supercomputer "Fuyue", which is equivalently faster than the Google released last year. The 53-bit quantum computing prototype "Platanus" is 10 billion times faster.

Behind this achievement, the team independently developed technologies such as quantum light sources with high efficiency, high identity, extremely high brightness and large-scale scalability.

  Quantum's large-scale interference technology, high-precision phase-locking technology and high-quality light source, and the high-performance superconducting single-photon detector developed by our Chinese Academy of Sciences Shanghai Microsystems, the current performance is also internationally the best.
