According to reports from CCTV News and Science and Technology Daily, China has recently released the world's first dual-core atomic quantum computer, "Hanyuan 2." This device is 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, with the core breakthrough being the advancement from a single-core to a dual-core architecture for the quantum processor.

The interior of Hanyuan 2 does not house traditional chips but instead controls 200 atoms through a precision optical system to perform calculations. These atoms are divided into two square arrays, forming a dual-core collaborative system where one array is responsible for computation and the other for real-time error correction, thereby simultaneously enhancing efficiency and stability during the computation process.

Science and Technology Daily states that Hanyuan 2 is based on an independently controllable neutral atom array technology, integrating 100 atoms of 87Rb and 100 atoms of 85Rb, to construct a dual-core collaborative computing system with a total of 200 quantum bits. Compared to Hanyuan 1, released two years ago, the accuracy of manipulated atoms has been improved from 90% to 99%, and the stable survival time of atoms has been extended from 20 seconds to over 100 seconds.

These indicators are directly related to whether quantum computing can operate continuously and reliably. More importantly, Hanyuan 2 does not require a cryogenic cooling system, with the entire machine consuming less than 7 kilowatts of power, allowing it to operate stably in a standard laboratory environment. For quantum computing devices, this means reduced maintenance conditions and operational barriers, also setting it apart from approaches that rely on extreme low-temperature environments.
