Quantum Key Distribution offers information theoretic security for the secret key agreement problem. However all the QKD networks deployed to date require a dedicated communication infrastructure, making it an expensive technology. They are mainly designed as a collection of point-to-point QKD links. Secret keys between non-neighbouring nodes are transmitted using the trusted repeater paradigm. Here we propose a network model in which multiple QKD systems use simultaneously quantum and classical communication channels that are wavelength multiplexed over a common communication infrastructure. The respective signals are transmitted using passive network components within a metropolitan area, thus removing expensive trusted intermediate nodes. The scheme is flexible, and can be used with different QKD devices designs and adapted to different scenarios, thus is a good candidate for standardization. The design belongs to the class of switched QKD networks in which quantum communication is end-to-end and potential security loopholes are avoided. The network is wavelength addressable: simultaneous communication is allowed in a dynamically-addressed any-to-any scheme. The proposed model resembles that of a commercial telecom network, takes advantage of existing fibre infrastructure and utilizes existing commercial components, allowing for an easy, cost-effective and reliable deployment. | |
