China has successfully developed its first dual-core atomic quantum computer, a project led by the Chinese Academy of Sciences in collaboration with teams from Wuhan University, Huazhong University of Science and Technology, and the Wuhan Institute of Quantum Technology. This quantum computer marks a significant upgrade by advancing the quantum processor from a single-core to a dual-core design, providing crucial support for China's pursuit of self-reliance in high-end computing capabilities.
Named "Hanyuan 2," this supercomputer operates without traditional chips. Instead, it uses a sophisticated optical system to control 200 atoms for computational tasks. According to technical experts, these 200 atoms function like 200 super-brains, divided into two groups to form a dual-core architecture—one group dedicated to computation and the other to real-time error correction, effectively doubling efficiency.
Compared to its predecessor, "Hanyuan 1," which was released two years ago, "Hanyuan 2" has improved atomic operation accuracy from 90% to 99% and extended atomic stability from 20 seconds to over 100 seconds. Additionally, the entire system consumes less than 7 kilowatts of power and operates stably in standard laboratory conditions without requiring cryogenic cooling systems. The research team has also established a comprehensive development chain covering chip production, packaging and testing, laser modulation, and phase noise suppression, achieving domestic production of core components.
Quantum computing is known to significantly enhance computational efficiency in specific fields such as cryptography, as well as having broad application prospects in areas like stock portfolio optimization, protein design, and new drug development. Currently, "Hanyuan 1" is already in operation on China Mobile's cloud platform and is set for export overseas, while "Hanyuan 2" is accelerating its commercialization process.
