量子密钥分发(QKD)正在迅速成熟。然而，目前在光网络中应用它的方法使其成为一项昂贵的技术。到目前为止部署的QKD网络被设计为点对点专用QKD链路的集合，其中非相邻节点使用可信中继器范例进行通信。我们提出了一种新的光网络模型，在该模型中，量子密钥分发系统通过对它们的量子信号和经典信号进行波长复用来共享通信基础设施。该路由使用城域内的光学组件来完成，这允许动态的任意对任意的通信方案。此外，它类似于商业电信网络，利用现有基础设施和商业组件，允许轻松、经济高效和可靠的部署。(C)2014年美国光学学会
Quantum Key Distribution (QKD) is maturing quickly. However, the current approaches to its application in optical networks make it an expensive technology. QKD networks deployed to date are designed as a collection of point-to-point, dedicated QKD links where non-neighboring nodes communicate using the trusted repeater paradigm. We propose a novel optical network model in which QKD systems share the communication infrastructure by wavelength multiplexing their quantum and classical signals. The routing is done using optical components within a metropolitan area which allows for a dynamically any-to-any communication scheme. Moreover, it resembles a commercial telecom network, takes advantage of existing infrastructure and utilizes commercial components, allowing for an easy, cost-effective and reliable deployment.
