大失谐J-C模型中腔耗散对量子态保真度的影响
Influence of the cavity dissipation on fidelity of quantum state in the large detune J-C model
摘要
Abstract
The fidelities of quantum states of system in Jaynes-Cummings model considering the dissipation of cavity were studied by using the complete quantum theory.The influences of the cavity damping constant and the numerical value of initial mean photon number on the fidelities of quantum states was discussed.It was found that both of them affect the fidelities of atom and of atom-cavity system obviously.关键词
