Abstract

Multiqubit quantum controlled-phase-flip (CPF) gate between atomic qubits is desirable for scalable and distributed quantum computation. Here, we propose a scheme to realize a multiqubit quantum CPF gate between different atoms, which are trapped in separate cavities coupled by short optical fiber. After a single-photon pulse reflected by the cavity-atoms system, a multiqubit CPF gate can be implemented by only one step.
