Research interests


My research interests are centred around quantum information processing and quantum communications, and in particular theoretical and experimental quantum cryptography, and quantum networks. My research within the Quantum Information team in Télécom ParisTech is organized in two main directions: the study of quantum networks - from the topology, optimization and security of currently available quantum cryptography networks to the implementation of advanced quantum networks containing elements such as quantum repeaters and quantum memories -, and the study of quantum cryptographic primitives other than key distribution that could present numerous applications in the future secure communication systems. These research objectives are pursued in the context of the research projects CRYQ, QUANTUM-WDM, and COMB, funded by the Agence Nationale de la Recherche, the European Union FP7 Marie-Curie IAAP project QCERT, the CHIST-ERA project HIPERCOM, and the Mairie de Paris Emergences project CiQWii.
