China unveils Hanyuan-2, the world’s first dual-core quantum computer
Unlike other models, the machine does not need to be kept at ultra-low temperatures and is easier to maintain
China has built the world’s first dual-core quantum computer, a development that could “significantly enhance” efficiency, according to official media.
The breakthrough signalled that Chinese quantum computing technology was “entering a new stage”, the state-owned Science and Technology Daily reported this week.
While other quantum computers rely on high energy consumption and need to be run in temperatures close to absolute zero, the design of this computer uses neutral atoms – which consume less energy and make the machine easier to maintain.
According to the report, the twin cores support parallel computing – a function compared to two brains operating together – and can divide tasks between them or correct each other’s errors.
The computer, dubbed Hanyuan-2, was developed by CAS Cold Atom Technology, a tech firm affiliated with the Chinese Academy of Sciences (CAS) and based in the central Chinese city of Wuhan.
Quantum computers perform calculations and solve complex problems using qubits – or quantum bits – a fundamental unit of information.
