We present a scheme for implementing a quantum teleportation process using the Jaynes–Cummings model. For this, we study the interaction between an excited state of a two-level atom and a single electromagnetic field in a superposition of coherent states. The resulting entangled state may be considered as a good quantum channel for quantum teleportation protocol. By controlling the interaction field parameters inside the cavity, the average fidelity of the teleported state may be maximized. However, the weight and phase parameters in the teleported states are estimated by using quantum Fisher information. It allows one to show that the sensitivity of the teleported states fluctuates between maximum and minimum bounds for large numbers of photons. Evaluating different quantities of quantum entanglement, average fidelity, and the amount of quantum Fisher information shows that the odd coherent states are usually larger than those obtained using even coherent states.

传送偶数和奇数相干态的量子Fisher信息

我们提出一种使用Jaynes-Cummings模型实施量子隐形传态过程的方案。为此，我们研究了两能级原子的激发态与相干态叠加中的单个电磁场之间的相互作用。所产生的纠缠态可以被认为是用于量子隐形传态协议的良好量子通道。通过控制腔体内的相互作用场参数，可以最大化传送状态的平均保真度。但是，通过使用量子Fisher信息来估计传送状态下的权重和相位参数。它允许人们证明，对于大量光子，瞬态状态的灵敏度在最大和最小范围之间波动。评估不同数量的量子纠缠，平均保真度，
