【Global Science and Technology Report】On May 3, the scientific and technological community ushered in an exciting news: The world’s first light quantum computer that surpassed the early classical computer was born in China! This indicates that the field of quantum computer research in China has entered. World class ranks. It is reported that this light quantum computer is jointly researched and developed by China University of Science and Technology, the Chinese Academy of Sciences-Alibaba Quantum Computing Laboratory, Zhejiang University, and the Institute of Physics of the Chinese Academy of Sciences, and is a genuine "Made in China."

Quantum computer refers to a computer that uses the principle of quantum coherent superposition and theoretically has ultra-fast parallel computing and simulation capabilities. If you compare a traditional computer to a bicycle, a quantum computer is like an airplane. The use of billions of "Tianhe 2" supercomputers to solve a billion-giga-volume system of equations takes 100 years. It takes only 0.01 second to solve the same equation with a trillion quantum computer.

Photovoltaic Quantum Computer Circuit Diagram Developed by the Chinese Academy of Sciences

According to Pan Jianwei, an academician of the Chinese Academy of Sciences, the research team built a photo quantum computing prototype on the basis of the realization of the ten-photon entanglement maneuver for the first time in 2016. The "brown bobbin sampling" speed of the prototype is 2.4 million times faster than that of the industry. Comparing with the classic algorithm, this photo quantum computing prototype has been found to run 10 to 100 times faster than the human first electronic tube computer (ENIAC) and the first transistor computer (TRADIC). It is expected that by the end of 2017, the research team will implement about 20 light qubit manipulations.

Superconducting Quantum Computer Roadmap

In addition, in the superconducting system, the research team broke the nine qubit manipulation records maintained by the United States, independently developed a 10-bit superconducting quantum circuit sample, and successfully achieved the largest number of superconducting qubits in the world. Pure entanglement, and complete description of the 10-bit quantum state by tomography.

Alibaba Quantum Computing Laboratory, Chinese Academy of Sciences

Two years ago, Alibaba and the Chinese Academy of Sciences established the first quantum computing laboratory in Asia to carry out forward-looking research in the field of quantum information science and explore the next-generation ultra-fast computing technology that goes beyond classical computers. The two sides soon achieved excellent results and brought quantum computing from the academic world to the real world. At the Yunnan Yunqi Conference in March this year, Alibaba Cloud announced the world’s first case of quantum encryption and communication on the cloud, and provided customers with unconditional secure data transmission services by establishing multiple quantum-safety transmission domains.

At a recent technology conference, Ma Yun announced the launch of Alibaba’s “NASA Plan” and stated that “the goal of the current study is to solve the difficulties of 10 years and 20 years.” Quantum computing is Alibaba’s solution for 20 years. After the calculation of resources scarce secret weapon.

It is estimated that by 2025, quantum computing will reach the level of the world’s fastest supercomputer and will be applied to some major technological problems that cannot be solved at present.
