The University of Science and Technology of China has scored a significant breakthrough in the realm of silicon-based semiconductor quantum computing. A research team from the university, working in tandem with Origin Quantum Computing Co., Ltd., has, for the very first time, successfully attained strong coupling between resonant exchange qubits (RX qubits) and high-impedance microwave resonators within silicon-based materials. The coupling strength soared to a remarkable 65.8 MHz, substantially outperforming the existing micro-magnet-based flip-flop mode spin qubit systems. This accomplishment sets a robust groundwork for the development of fully electrically controlled, scalable silicon-based quantum processors and quantum networks.
