量子计算机网络中的量子复用技术

Quantum Multiplexing for Quantum Computer Networks

Juan Carlos Garcia-Escartin, Pedro Chamorro-Posada

摘要:

在通信网络中,许多不同的信道必须共享有限量的资源。为了允许多个同时通信,通常采用多址技术。通过量子通信,可以共享一种新的资源。所有的系统通道可以容纳到一个更大的希尔伯特空间中的单个通道。在该方案中,一条线路组合了所有用户的信息,并且在接收端,原始的量子信道被恢复。给定的复用器/解复用器电路可以执行该n个量子比特到量子比特的变换。超密集编码和经典的多址接入方案的连接进行了讨论。

英文摘要:

In communication networks many different channels must share a limited amount of resources. In order to allow for multiple simultaneous communications, multiple access techniques are routinely employed. With quantum communication, it is possible to share a new kind of resource. All of the system channels can be accommodated into a single channel in a larger Hilbert space. In the scheme, a single line combines the information of all the users, and, at the receiver, the original quantum channels are recovered. The given multiplexer/demultiplexer circuit can perform this n qubits to qudit transformation. Connections with superdense coding and classical multiple access schemes are discussed.
