摘要 运用全量子理论,研究了考虑Stark效应的Jaynes Cummings(J C)模型中的量子态保真度,讨论了Stark效应对量子态保真度的影响。结果表明,初始平均光子数的大小和Stark效应的强度可调制相互作用体系的量子态保真度。 The fidelities of quantum states of system in JaynesCammings(JC) model considering the Stark effect were studied by using the complete quantum theory.The influence of the Stark effect on the fidelities of quantum states was discussed.It is shown that both the numerical value of initial mean photon number and the strength of Stark effect can modulate the fidelities of quantum states in the system of interaction.
