Chinese scientists design 62-qubit quantum processor
A team of researchers from the University of Science and Technology of China has designed a 62-qubit programmable superconducting quantum processor, called Zu Chongzhi. The processor was presented as marking two significant milestones in the field of quantum computing: (a) containing the largest number of superconducting qubits so far in the world, and (b) achieving two-dimensional programmable quantum walks. According to Global Times, the researchers designed and produced a 8×8 two-dimensional square superconducting qubit array composed of 62 functional qubits, and used this device to demonstrate high fidelity single and two particle quantum walks. This achievement is said to bring future larger scale quantum applications closer to realisation on noisy intermediate-scale quantum processors.
