CAS Firm Unveils Hanyuan2 Dual-Core Neutral Atom Quantum Computer

CAS Cold Atom Technology, a Wuhan-based firm affiliated with the Chinese Academy of Sciences, has unveiled Hanyuan2, which it describes as the world's first dual-core neutral atom quantum computer.

The system features 200 qubits formed by two independent arrays of 100 rubidium-85 atoms and 100 rubidium-87 atoms, housed in a single cabinet-sized machine. The dual cores can operate in parallel to divide computational workloads or in a main-auxiliary mode, with the secondary array performing real-time error correction for the primary one. Company officials stated that this architecture marks the first shift from single-core to dual-core design in quantum processors.

Ge Guiguo, a senior expert at the firm, told reporters that Hanyuan2 represents a key advancement in neutral atom technology, which uses laser arrays to trap, cool, and manipulate uncharged atoms as qubits. Unlike superconducting or trapped-ion systems that demand temperatures near absolute zero and high energy use, neutral atom platforms like Hanyuan2 operate with laser cooling at higher temperatures, making them more energy-efficient and easier to deploy.
