Quantum Laboratory

The research team composed of Pan Jianwei, Lu Chaoyang and Liu Naile from the Institute of Quantum Information and Quantum Technology Innovation of the Chinese Academy of Sciences of the University of Science and Technology of China, in cooperation with the Shanghai Institute of Microsystems and Information Technology of the Chinese Academy of Sciences and the National Research Center for Parallel Computer Engineering Technology, has developed the theory and experimental methods of stimulated amplification of quantum light sources, built a 113 photon 144 mode quantum computing prototype "Jiuzhang No.2", realized the phase programmable function, and completed the rapid solution of the Gaussian Bose sampling task used to demonstrate the "superiority of quantum computing". According to the officially published optimal classical algorithm theory, the processing speed of Gaussian Bose sampling in "Chapter Nine No. 2" is 10 ^ 24 times faster than the fastest supercomputer currently available. This achievement once again refreshed the international level of optical quantum manipulation technology and provided further experimental evidence for quantum computing acceleration.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Quantum computers utilize many characteristics of quantum systems, such as quantum superposition and entanglement, to surpass traditional classical computers in processing speed for some complex tasks. The team led by Pan Jianwei from the University of Science and Technology of China has made significant progress in this field: in 2020, they successfully constructed the "Nine Chapters" quantum computing prototype with 76 photons, achieving quantum superiority; In 2021, "Jiuzhang-2" was ten times faster than supercomputers in handling specific problems to the power of twenty-four; In 2023, the "Nine Chapters Three" will further break records, solving specific mathematical problems 100 billion times faster than the world's fastest supercomputer, marking an important step forward in the development of quantum computers.
