Engineered Quantum Systems for Quantum Information

近年来，量子信息科学发展迅速，量子密码系统已经商业化。这些系统是量子通道的一个例子，主要用于分发量子信息。目前正在进行一项重大努力，将这些量子通道与量子节点相结合，以提供基本的存储、处理和路由能力。这些通道和节点的组合将创建一个完全量子的网络，使今天根本不可能实现的应用成为可能。连接简单量子处理节点的量子网络也是一种很有前途的可扩展量子计算机体系结构。

In recent years, quantum information science has advanced rapidly, with quantum cryptography systems already commercially available. These systems are an example of quantum channels, serving mainly to distribute quantum information. There is a significant effort underway to combine these quantum channels with quantum nodes that would offer basic memory, processing and routing capability. The combination of these channels and nodes would create a fully quantum network, enabling applications simply impossible today. Quantum networks connecting simple quantum processing nodes are also a promising architecture for a scalable quantum computer.
