Three-qubit phase gate on three modes of a cavity

We show that a three-qubit phase gate on three modes of a cavity can be realized via resonant atom–cavity interaction. By introducing two strong classical fields and modulating the amplitudes, we obtain the effective form of nonlinear interaction between photons in the three-mode cavity. The availab...

Description
Summary:We show that a three-qubit phase gate on three modes of a cavity can be realized via resonant atom–cavity interaction. By introducing two strong classical fields and modulating the amplitudes, we obtain the effective form of nonlinear interaction between photons in the three-mode cavity. The availability is testified via numerical analysis. We also consider both the situations with and without effect of decoherence.
