Title: Quantum trajectory simulation of controlled phase-flip gates using the vacuum Rabi splitting

Abstract

The atom-photon controlled phase-flip gates using vacuum Rabi splitting proposed by Duan and Kimble [Phys. Rev. Lett. 92, 127902 (2004)] are simulated by a quantum trajectory approach. Atomic nonradiative dephasing and intracavity loss due to absorption and scattering by cavity mirrors are taken into account in addition to atomic spontaneous emission. The gate fidelity calculated by the trajectory approach is compared with that obtained by a simple amplitude-damping model. The gate fidelity under the condition of no photon loss is also discussed.
