Twenty years long background in Quantum communication and QRNGs
Professor Villoresi leads the first pioneering experimenent demonstrating single-photon exchange between a satellite and a ground station on Earth [NJP (2008)].
This demonstration was followed by a proposal for the mitigation of turbulence effects in a QKD experiment between two Canary islands separated by 143 km [PRA (2015)], the first demonstration of Quantum Communications from an orbiting transmitter on a LEO satellite using polarization [PRL 2015] and temporal degrees of freedom [PRL 2016], fundamental experiments in wave-particle duality of photons in Space [SciAdv 2017], and single photon exchange from a MEO [PRA 2016] and GNSS satellites [QST 2019].
The group recently proposed new devices for fiber and free-space QKD: the POGNAC polarization encoder [OL 2019] and its improved version iPOGNAC [OL 2020] show intrinsic long-term stability and record quantum bit error rate [Optica 2020]. The above devices, together with a novel syncronization techique for QKD – Qubit4Sync – presented in [PRApp 2020], were recently tested in a field-trial experiment in the first network installed at the University of Padova [ArXiv].
The group is currently involved in several national and international projects:
- the I-QKD Italian quantum communication in-orbit validation satellite funded by the Italian Space Agency (ASI) [Villoresi Principal Investigator];
- the QSecGroundSpace project funded by ASI with the aim of developing new QKD protocols and the interconnection between fiber and space QKD networks [Villoresi Principal Investigator];
- OpenQKD EU Testbed for Quantum Communications [Villoresi Italian node coordinator];
- EU project QUANGO aiming at the development of the components for a CubeSat with QKD and 5G capability [Vallone Project Leader];
- project QUASAR with the objectives of development of new methods for the realization of ultra-fast and secure QRNGs [Vallone Project Leader].
