Werner态的纠缠隐形传态

Entanglement Teleportation via Werner States

Jinhyoung Lee, M. S. Kim

摘要:

研究了未知纠缠态通过噪声量子信道的量子隐形传态的纠缠和信息传递。我们发现,即使信道是量子关联的,未知态的量子纠缠也会在隐形传态过程中丢失。我们引入了一个基本参数的相关信息,通过噪声信道的隐形传态过程中线性耗散。通过分析关联信息的传递,我们发现初始态的纯度对复制态的纠缠度有重要影响。

英文摘要:

Transfer of entanglement and information is studied for quantum teleportation of an unknown entangled state through noisy quantum channels. We find that the quantum entanglement of the unknown state can be lost during the teleportation even when the channel is quantum correlated. We introduce a fundamental parameter of correlation information which dissipates linearly during the teleportation through the noisy channel. Analyzing the transfer of correlation information, we show that the purity of the initial state is important in determining the entanglement of the replica state.
