CAS Cold Atom Technology, a Wuhan-based quantum computing company affiliated with the Chinese Academy of Sciences (CAS), has unveiled a dual-core neutral atom quantum computer dubbed Hanyuan-2. The company claims the 200-qubit system is the first of its kind globally, with its dual-core framework designed to address limitations around scalability and interference. Comprising 100 rubidium-85 and 100 rubidium-87 neutral atoms, Hanyuan-2 works by splitting workloads across the system’s two arrays, allowing each to compute different aspects of a problem simultaneously or perform error correction on one another. Furthermore, because neutral atom-based quantum computers don’t need to be cooled to near absolute zero temperatures, like superconducting or trapped ion systems, Hanyuan-2 can operate at room temperature, with its integrated cabinet design cooled by a small laser system. This has resulted in a significant reduction in the system’s power consumption – below 7kW, the company claims. All the information regarding the Hanyuan-2 was reported by Chinese state-affiliated media outlets, and no additional metrics that would verify the claims have been published. Neutral atom quantum computing is a modality that involves controlling individual, charge-neutral Rydberg atoms with laser-based "optical tweezers.” In March 2026, Google announced it would be expanding its quantum computing efforts to include a neutral atom approach, having previously focused on the development of superconducting qubits for more than a decade. At the time, the company said its neutral atom program would be built on three pillars: quantum error correction, modeling and simulation, and experimental hardware development. Comments
