通过量子链路进行通信

Communication Through a Quantum Link

Vittorio Giovannetti, Daniel Burgarth, Stefano Mancini

摘要:

相互作用的自旋链的行为就像量子中介(量子链路),它允许控制链末端的两个遥远的方交换量子消息。我们发现,在不重置量子链路的研究的情况下,过度重复使用可以连接到具有有限维环境的相关量子信道(有限存储量子信道)。然后,使用这种信道的编码参数和混合信道的结果,我们提出了一个协议,使我们能够通过量子链路实现完美的信息传输。

英文摘要:

A chain of interacting spin behaves like a quantum mediator (quantum link) which allows two distant parties that control the ends of the chain to exchange quantum messages. We show that over repeated uses without resetting the study of a quantum link can be connected to correlated quantum channels with finite dimensional environment (finite memory quantum channel). Then, using coding arguments for such kind of channels and results on mixing channels we present a protocol that allows us to achieve perfect information transmission through a quantum link.
