Chinese team Designs 62-Qubit Quantum Processor with World’s Largest Number of Superconducting Qubits

(GlobalTimes.cn) A Chinese research team the University of Science and Technology of China (USTC)has successfully designed a 62-qubit programmable superconducting quantum processor, naming it Zu Chongzhi after the noted 5th century Chinese mathematician and astronomer. The computer contains the largest number of superconducting qubits so far in the world, and achieved two-dimensional programmable quantum walks on the system, a major milestone in the field. The study was published Friday in Science magazine.
The team designed and produced an 8×8 two-dimensional square superconducting qubit array composed of 62 functional qubits in the study, and used this device to demonstrate high fidelity single and two particle quantum walks, according to the team.
The work was an essential milestone, bringing future larger scale quantum applications closer to realization on noisy intermediate-scale quantum processors, said the team in the article.
