摘要：

A scheme is proposed to generate GHZ state and realize quantum phase gate for superconducting qubits placed in a microwave cavity.This scheme uses resonant interaction between the qubits and the cavity mode,so that the interaction time is short,which is important in view of decoherence.In particular,the phase gate can be realized simply with a single interaction between the qubits and the cavity mode.With cavity decay being considered,the fidelity and success probability are both very close to unity.
