Abstract

The coexistence of QKD and classical communication systems is described, identifying the principal limitations to its practical realization. The relevance of SDN as a suitable approach for a real integration between QKD and WDM networks is presented, together with the description of novel rateless error correcting codes (ECC) suitable for QKD reconciliation. Preliminary experimental results on a discrete-variable QKD field trial, over production optical fibers deployed in the metropolitan area of Turin in presence of high-bitrate classic channels, are reported. Stable performance on a week-long interval is demonstrated, showing the capabilities of QKD in short/medium reach optical networks. This work is part of the activities of the PON project "Development of quantum systems and technologies for IT security in communication networks" (QUANCOM) which aims to the realization of a metropolitan quantum communication network through the collaboration between universities, research centers and companies operating in the communication market area.
