China Completes First Dual-Core Atomic Quantum Computer Controlling 200 Atoms

GateNews

China’s Academy of Sciences and partner institutions completed the nation’s first dual-core atomic quantum computer, codenamed Hangyuan 2, according to monitoring by Beating. The system uses precision optical technology to control 200 atoms for computation, split into two arrays for dual-core architecture—one for calculation, one for real-time error correction. Compared to Hangyuan 1 released two years ago, the new system improved atom operation accuracy from 90% to 99% and extended atom stability from 20 seconds to over 100 seconds. The entire system consumes less than 7 kilowatts and requires no cryogenic cooling, enabling stable operation in standard laboratory environments.
