摘要

The key mechanism which enables two-qubit operations of a hybrid quantum processing unit for hybrid quantum computing is demonstrated. A scheme which realizes a disguised switch for two-qubit gating is proposed, combining external magnetic field control, quantum dot sample tuning, and assisted laser control. Our methods overcome the limitation of asynchrony between single-qubit operations of respective solid-state qubits and improve the efficiency of single-qubit gating.
