This makes the technology expensive and hard to deploy. In this letter, we show an easy and straightforward integration method of quantum cryptography into optical access networks. In particular, we analyze how a quantum key distribution system can be seamlessly integrated in a standard access network based on the passive optical and time division multiplexing paradigms. The novelty of this proposal is based on the selective post-processing that allows for the distillation of secret keys avoiding the noise produced by other network users. Importantly, the proposal does not require the modification of the quantum or classical hardware specifications neither the use of any synchronization mechanism between the network and quantum cryptography devices. date: 2014-05 date_type: published official_url: http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6762880 id_number: 10.1109/LPT.2014.2308921 full_text_status: public publication: IEEE Photonics Technology Letters volume: 26 number: 9 pagerange: 881-884 institution: ETSI_Informatica department: Matematica_Aplicada refereed: TRUE issn: 1041-1135 rights: by-nc-nd citation: Martinez Mateo, Jesus and Ciurana Aguilar, Alex and Martín Ayuso, Vicente (2014).
