China's Zuchongzhi 3.0 Quantum Prototype Achieves Breakthrough, Outperforming Google's Sycamore by a Million Times

Chinese quantum physicists have unveiled the Zuchongzhi 3.0 prototype, boasting 105 qubits and 182 couplers. It performs random quantum circuit sampling tasks a quadrillion times faster than advanced supercomputers. * The prototype is one million times faster than Google's Sycamore prototype, as published in Nature in October 2024. * Quantum computational advantage, or "quantum supremacy," is when quantum computers outperform classical supercomputers on specific tasks. * The U.S. and China lead quantum computing research, with the U.S. achieving "quantum supremacy" in 2019 with "Sycamore," and China in 2020 with "Jiuzhang." * Zuchongzhi 3.0 marks a significant advancement in processing capacity compared to its predecessor.
