单库珀对盒中的最大纠缠态和量子隐形传态

Maximum entangled states and quantum Teleportation via Single Cooper pair Box

N. Metwally, A. A. El-Amin

摘要:

本文研究了单库珀对盒与单腔模的相互作用。给出了失谐量和带电容量对纠缠度的影响。当失谐量较大时,纠缠度越大,生存纠缠越大。我们产生了一个最大纠缠态,并使用它来执行原来的隐形传态协议。随着失谐量的减小和腔内光子数的减少,量子态的保真度增加。

英文摘要:

In this contribution, we study a single Cooper pair box interacts with a single cavity mode. We show the roles played by the detuning parameters and charged capacities on the degree of entanglement. For large values of the detuning parameter the survival entanglement increases on the expanse of the degree of entanglement. We generate a maximum entangled state and use it to perform the original teleportation protocol. The fidelity of the teleportated state is increased with decreasing the detuning parameter and the number of photon inside the cavity.
