摘要
运用全量子理论对二项式光场和二能级原子相互作用模型中保真度的演化特性进行了研究,发现二项式光场的初始光子数和失谐量对保真度有明显的影响.结果表明,初始时刻二项式光场的平均光子数越大,保真度就越小;失谐量越大,保真度就越大.
The properties of the evolution of the fidelities under the interaction of binomial state for radiation field with two-level atom have been investigated.The influences of average photons and detuning on the fidelity have been discussed.The numerical results show that the more the average photons are,the lower the fidelities are;the higher detuning value is,the higher the fidelities are.
