摘要：

We show how the quantum Zeno effect can be exploited to implement the CNOT gate in two separated cavities with two atomic four-level tripod systems. In respective subspaces of the total Hilbert space, the evolution of the quantum system exhibits different dynamical properties due to the continuous coupling between atoms and cavities. The strictly numerical simulation reveals that a high average gate fidelity can be obtained in the presence of decoherence. (C) 2009 Optical Society of America
