Multimode Quantum Optics - Multimode Quantum Optics

Research

In the multimode quantum optics group, we study the fundamental quantum properties and applications of light with many degrees of freedom (i.e. modes). Our activities are both theoretical and experimental, and the applications we consider range from quantum-inspired metrology and imaging, all the way to quantum information processing. We are mainly interested in the continuous-variable approach to light, which means that we rely on measurements of the electromagnetic field itself through homodyne detection.

Femtosecond Quantum Information

Multiplexing in time and frequency allows us to create large and versatile entangled states using quantum frequency combs. We use pulse shaping techniques to implement mode-selective measurements and operations (such as photon subtraction).

Quantum Complex Networks

Replicating complex networks in a scalable quantum platform is a formidable opportunity to learn more about the intrinsic quantumness of real world and for the efficient exploitation of quantum-complex structures in future technologies.

Quantum-inspired Metrology

Adapting many ideas and techniques from quantum optics to the field of imaging. We are specialised in the use of spatial-mode demultiplexing in such applications.
