Pan Jianwei, Zhu Xiaobo, Peng Chengzhi and other researchers from the University of Science and Technology of China, in cooperation with the Shanghai Quantum Science Research Center, the Henan Provincial Key Laboratory of Quantum Information and Quantum Cryptography, the China Institute of Metrology, the Jinan Institute of Quantum Technology, the School of Microelectronics of Xidian University, and the Institute of Theoretical Physics of the Chinese Academy of Sciences, have successfully built a 105-bit (including 105 readable bits and 182 coupled bits) superconducting quantum computing prototype "Zu Chongzhi No. 3", which has achieved rapid solution to quantum random circuit sampling tasks. Compared with the existing optimal classical algorithm, "Zu Chongzhi No. 3" processes quantum random circuit sampling problems 15 orders of magnitude faster (10 to the 15th power times) than the fastest supercomputer currently, and 6 orders of magnitude (10 to the 6th power times) faster than the latest results published by Google in October 2024. This achievement is the second time that my country has broken the record of quantum computing superiority of superconducting systems after the superconducting quantum computing prototype "Zu Chongzhi No. 2" achieved the strongest quantum computing superiority of superconducting quantum computing systems. The relevant results were published online in the international academic journal Physical Review Letters on March 3, Beijing time.
