Deploying QKD in Standard Optical Networks

Daniel Lancho Lancho, Jesús Martínez-Mateo, David Elkouss +3 more

In order to deploy QKD in a cost effective and scalable way, its integration with already installed optical networks is a logical step. If, for the sake of security, we require that no intermediate trusted nodes would be needed, the maximum distance/absorptions allowed by QKD systems limit ourselves to metropolitan area networks. Current metro networks are mostly all optical and passive, hence a transparent link can be established among any two points and this link can be used to transport the quantum channel. In this poster we report on our findings studying the problems arising when integrating QKD systems in standard telecommunications networks.In order to deploy QKD in a cost effective and scalable way, its integration with already installed optical networks is a logical step.

Gigahertz-clocked quantum key distribution in passive optical networks

Verónica Fernández, Robert J. Collins, Karen J. Gordon +2 more

In this paper we demonstrate the application of multi-user quantum key distribution (QKD) to typical broadband fibrebased passive optical access links to metropolitan area networks. We propose a technique to utilize the currently unused 850nm waveband in standard telecommunications fiber for QKD in two network architectures. Net bit rates of up to 100's of kilobits-1 were achieved for each receiver, depending on the network topology. The transmission distances between sender and receivers were compatible with the typical span of optical access links ( ≤ 10km).In this paper we demonstrate the application of multi-user quantum key distribution (QKD) to typical broadband fibrebased passive optical access links to metropolitan area networks.

Demonstration of Software Defined Network Services Utilizing Quantum Key Distribution Fully Integrated with Standard Telecommunication Network

Diego R. Lopez, Vicente Martín, Vı́ctor López +13 more

We present a demonstration of software defined networking (SDN) services utilizing quantum key distribution (QKD) technology, fully integrated with standard telecommunication network connecting production facilities of Telefonica in Madrid. All communications “co-propagate” over the same fiber infrastructure.
