China unveils 200-qubit Hanyuan-2 dual-core quantum computer, consumes less than 7kW of power

China unveiled Hanyuan-2, a 200-qubit quantum computer built on a dual-core neutral-atom design.

The system reportedly runs on under 7 kW, aiming for better efficiency, stability, and error handling.

Its creators say the architecture is more practical for industrial applications than lab-scale prototypes.

The launch highlights growing progress toward commercially usable, energy-efficient quantum computing.
