China launches Hanyuan-2: World's first dual-core quantum computer with 200 qubits

China's CAS Cold Atom Technology announced Hanyuan-2, the world's first dual-core quantum computer, marking a significant advancement in computational power and energy efficiency.

Unlike competitors requiring extreme cooling to near absolute zero temperatures, Hanyuan-2 uses neutral atoms, uncharged particles that dramatically reduce power consumption and operational complexity.

This development marks a new era for China's quantum technology, according to the official newspaper of Science and Technology Daily. The dual-core design allows for parallel computing by utilising two cores at the same time, either to compute different aspects of a problem or correct each other's mistakes, which can expedite the use of quantum computers in different sectors.

Hanyuan-2 uses 200 qubits, which is the basic unit of quantum computing. The supercomputer reaches "world-class levels" in several critical parameters, including the qubit lifespan, using less than 7 kilowatts of energy.

This efficiency allows operation in ordinary conditions rather than ultra-low-temperature environments required by competing systems using ions, photons, or artificial atoms.

"The Hanyuan-2 adopts a standard cabinet-style integrated design and only requires a small laser cooling system to operate," said Tang Biao, the company's general manager. The compact footprint and minimal power requirements make quantum computing deployment more practical for industrial applications.
