One-step implementation of a multiqubit controlled-phase-flip gate

We propose a scheme for implementing quantum computation with N atoms trapped in a single-sided cavity. In our scheme, a multiqubit controlled-phase-flip (MCPF) gate as well as a quantum controlled phase flip gate is performed by only one step. The numerical simulations show that the protocol is robust to practical noise. In addition, the scheme can also be extended to achieve other multiqubit controlled unitary gates, and implement MCPF gate on atoms trapped in different cavities.
