Quantum Communications






Description

Our research aims to address the practical challenges of quantum communication towards its full integration in the already existing fiber networks. With the increasing amount of sensitive data and confidential information that are continuously transmitted around the globe, the security of communications is becoming more and more important. However, commonly used cryptographic technologies rely only on the computational limitations of current machines, which could be suddenly broken by new algorithms and, at the same time, by the advancement of quantum computers. Quantum Cryptography or Quantum Key Distribution (QKD) is nowadays the sole technology able to guarantee the unconditional security of communications. QKD relies on the physical laws and principles of Quantum Mechanics, whose validity is unaffected by the increasing computational power of future machines.

Besides crucial to guarantee information security, quantum communications, will be important for the future quantum networks, where emerging quantum devices, like quantum-enhanced sensors, quantum simulators, and powerful quantum computers, will be linked together through optical fiber networks and free-space links. In this framework, we aim to develop non-classical light sources to implement quantum information protocols. To move steps in this direction, we are studying efficient and telecom-compatible sources of entangled states. We are also aiming to generate entangled states able to be efficiently manipulated and mapped into a quantum memory: a milestone for quantum repeaters and long-distance quantum communications.
