摘要
通过对海森堡模型中量子热纠缠的研究,进而研究以海森堡热纠缠混合态为信道的量子隐形传递,计算出纠缠度和保真度,分析外界环境(温度、磁场等)对热纠缠及隐形传递的影响。
In this paper, we study quantum entanglement in Heisenberg model in the first; with that, the quantum teleportation via Heisenberg thermally entangled state is studied also. And then the concurrence and the fidelity are calculated. Finally the entanglement teleportation interacting with exoteric environment is analysed.
