AbstractWe propose an alternative scheme for one-step implementing three-qubit controlled phase-flip gate of spin qubits in spatially separated double quantum dots with a superconducting stripline resonator (SSR). Due to the switchable coupling effect between the double quantum dots and SSR, the present scheme could be easily generalized for multi-qubits. The feasibility of the present scheme is characterized by exact numerical simulations that incorporate various sources of experimental noise. Our results show the possibility to realize this proposed scheme within current experimental technologies.
