Ten million times faster than supercomputers! Important progress in quantum computing research in China

最近，中国科学院量子信息与量子科技创新研究所的科研团队在超导量子和光量子系统的量子计算方面取得了重要进展，使中国成为世界上唯一一个实现量子计算里程碑的国家两个物理系统中的"量子计算的优越性"。

Recently, the scientific research team of the Institute of quantum information and Quantum Science and technology innovation of the Chinese Academy of Sciences has made important progress in quantum computing of superconducting quantum and light quantum systems, making China the only country in the world to reach the milestone of "superiority of quantum computing" in the two physical systems.

超导量子计算研究团队攻关后，构建了66位可编程超导量子计算原型"祖冲之2"，实现了"量子随机线采样"任务的快速解决，比目前速度最快的超级计算机快1000万倍，而且计算复杂度比谷歌超导量子计算原型"铃木"高100万倍，这使中国首次在超导系统上达到"量子计算优势"的里程碑。

After tackling key problems, the superconducting quantum computing research team has built a 66 bit programmable superconducting quantum computing prototype "Zuchongzhi 2", which has realized the rapid solution of the task of "quantum random line sampling", which is 10 million times faster than the fastest supercomputer at present, and the computational complexity is one million times higher than Google's superconducting quantum computing prototype "Suzuki", It makes China reach the milestone of "superiority of quantum computing" in superconducting system for the first time.

同时，光量子计算研究团队构建了113光子144模量子计算原型"第9-2章"，其处理特定问题的速度比超级计算机快数十亿倍，提高了光量子计算原型的编程和计算能力。

At the same time, the light quantum computing research team has built a 113 photon 144 mode quantum computing prototype "chapter 9-2", which can handle specific problems billion times faster than supercomputers, and enhance the programming and computing ability of the light quantum computing prototype.

中国科技大学卢超洋教授：我们把前九章光量子计算机从76光子增加到113光子，比超级计算机快1000亿倍。

Professor Lu Chaoyang, University of science and technology of China: we have increased the previous nine chapter light quantum computer from 76 photons to 113 photons, 100 billion times faster than supercomputers.

超导量子比特和光学量子比特是国际公认的物理系统，有望实现可扩展的量子计算。量子计算机对特定问题的解决超越了超级计算机的优势，即量子计算。这是量子计算发展的第一个里程碑。

Superconducting qubit and optical qubit are internationally recognized physical systems that are expected to realize scalable quantum computing. The solution of specific problems by quantum computer surpasses the superiority of supercomputer, that is, quantum computing. It is the first milestone in the development of quantum computing.

中科院院士潘建伟：下一步，我们希望通过四到五年的努力，实现量子纠错。在利用量子纠错的基础上，我们可以探索利用一些特殊的量子计算机或量子模拟器来解决一些具有重大应用价值的科学问题。（中央台记者帅俊泉安徽方田）

Pan Jianwei, academician of the Chinese Academy of Sciences: in the next step, we hope to realize quantum error correction through four to five years of efforts. On the basis of using quantum error correction, we can explore using some special quantum computers or quantum simulators to solve some scientific problems with great application value.
