Hi there! For brief info on my academic career see my departmental website.

My Research (at a glance)

I am a theoretical physicist and computer scientist with main background in quantum mechanics, quantum optics and information theory. Most of my research activity has been devoted to quantum information theory, in particular with "continuous-variable systems".

Topics of main interest in random order:

        • Quantum Cryptography
        • Quantum Entanglement and Teleportation
        • Quantum Hypothesis Testing
        • Measurement Theory
        • Quantum Technologies
        • Relativistic and Black Hole Quantum Information
        • Capacities of Quantum Channels
        • Quantum Error Correction
        • Opto-Mechanical Systems
        • Quantum Networks
