Chinese team makes new breakthrough in quantum computing technology


Chinese researchers have made a new breakthrough in quantum computing technology.

A group of researchers from the University of Science and Technology of China (USTC) have designed and fabricated a programmable superconducting quantum computer prototype with the largest number of functional qubits in the world – 62, and achieved two-dimensional programmable quantum walks on the system, according to the university.

The study, led by renowned Chinese quantum physicist Pan Jianwei, was published in the top scientific journal Science on Friday. The computer prototype was named Zu Chongzhi after the accomplished Chinese mathematician from the fifth century.

“Quantum walks are the quantum mechanical analog of classical random walks and an extremely powerful tool in quantum simulations, quantum search algorithms, and even for universal quantum computing,” the authors wrote.

They called their work a milestone that brings future larger scale quantum applications…
