Multiplexed control scheme for scalable superconducting quantum processor

In this research, we present a multiplexed control scheme compatible with state-of-the-art superconducting qubit technologies, addressing critical challenges in large-scale quantum information processing. Our design allows simultaneous precise control of multiple qubits and couplers through shared control lines, markedly reducing wiring complexity, cooling power and space requirements. We also provide variant solutions according the gate type and qubit type. We expect the demand for control lines can be reduced by 1-2 orders of magnitude in the near future, presenting a promising pathway for scaling up quantum processors.
