QuantaQuest

A major challenge for today’s communication networks is to ensure safeexchange of sensitive data between distant parties. However, the rapiddevelopment of quantum information protocols towards the quantumcomputer poses a substantial threat for current cyber-security systems. Infact, quantum routines such as Shor’s factorization algorithm couldpotentially render today’s cryptographic schemes obsolete andcompletely insecure. Fortunately, quantum key distribution…

Atom interferometers have proven very successful in precision measurements such as the determination of the fine structure constant, the determination of the Newtonian gravitational constant, and inertial sensing of gravity, gravity gradients and rotation. They also show great promise to perform general relativity tests, including the weak equivalence principle. In parallel, atom chips provide a…

Our research project is focused on the development of a single photon source based on third order non-linearity in a cell of 87 Rubidium atoms through Four-Wave-Mixing process (FWM). In this process, a pair of co-propagating beams, a pump and a coupling, interact with the atomic ensemble and generate Stokes and anti-Stokes photon pairs. To…

QuantaQuest or less briefly Quantum secure communication and navigation for European defence is a project aiming to contribute to the applicability of quantum technologies in the military field and to the strategic autonomy of Europe. Navigation and timing will be achieved through a fully autonomous sensor based on cold atom chip and photonic integrated circuit…
