Quantum Communications

Quantum communications are not only important to guarantee unconditional information security, but they are also crucial to establish quantum networks, where emerging quantum devices, like quantum-enhanced sensors, quantum simulators, and quantum computers, can be linked together through quantum information protocols.

In this context, our research is focused to address the practical challenges of quantum key distribution either towards its full integration in the already existing fiber networks or through free-space optical links. Furthermore, we aim to develop non-classical light sources for efficient quantum information protocols, such as telecom-compatible entangled state and squeezed light sources. Also, our target is to generate photon entangled states able to be efficiently manipulated and mapped into a quantum memory: a milestone for quantum repeaters and long-haul quantum communications.
