Quantum Communication
Technology Group

In particular the main topics of investigation are quantum key distribution and quantum randomness generation. The Quantum Communication Technology Group focuses its research on the development and study of novel quantum technologies for secure communication.

The aim is to study different approaches to quantum communication on both a fundamental and a technological level, with an emphasis on applications in a telecom environment.

In particular the main topics of investigation are quantum key distribution and quantum randomness generation.
