ProjectsQuantum CommunicationCV-QKD

Quantum key distribution (QKD)

We will lead efforts to develop a low-cost, compact, and high-speed CV-QKD prototype that operates over distances of up to 50 km. This link will be used to explore several open issues in CV-QKD protocols, mainly related to side channel attacks. Subsequently, CV-QKD will be implemented independently of the employed measurement device (EMD), thus increasing the security of the previously developed system. Finally, the first CV-QKD-EMD field demonstration will take place, paving the way for a secure CV-QKD network and the deployment of this technology on a large scale.

Prof. Dr. Hugues de Riedmatten

Hugues de Riedmatten is ICREA professor and head of the Quantum Photonics group at ICFO since 2010. He obtained his PhD from the University of Geneva in 2003, where he worked as a Principal Scientist until 2010 after a two-year post-doctorate at the California Institute of Technology. His research focuses on the science of experimental quantum information and quantum optics. His group is developing quantum technologies to implement quantum networks and quantum repeaters for long-distance quantum communication, including quantum memories for light, quantum light sources, and quantum frequency conversion (www.qpsa.icfo.es). His research was awarded the City of Barcelona Prize in Experimental Science and Technology in 2017, a Start-up Grant from the European Research Council and a research grant from the Moore Foundation.
