A team of Chinese researchers has demonstrated that they have the world’s most powerful quantum computer known as 'Zuchongzhi', having 66-qubit quantum computing speed, surpassing the previous record holder - Google's Quantum computer Sycamore, which has 56-qubit speed. While, IBM's Q System One chip packs 20 qubits.

Zuchongzhi is a 2D programmable computer that can simultaneously manipulate up to 66 qubits.


The quantum computer was developed by a team led by Jian-Wei Pan at the University of Science and Technology of China in Shanghai and has 11 rows and 6 columns of qubits forming a two-dimensional rectangular lattice pattern. The quantum computer has solved a problem in just over an hour that would take the world’s most powerful classical supercomputer eight years to crack.

Google's Sycamore quantum computing processor with 53 qubits is said to be the first to achieve the so-called quantum supremacy, in 2019. Google's Sycamore reportedly did the task in 200 seconds that would have apparently taken a supercomputer 10,000 years to complete. Google's Sycamore was followed by China's 53-qubit Jiuzhang, which is a predecessor of Zuchongzhi.

Quantum Supremacy is a term used to describe a quantum chip that can solve a task that no typical supercomputer can process in any reasonable amount of time
