Quantum Key Distribution (QKD) relies on the ability to send quantum information over a communication link with minimal disturbance, and hence bounded information leakage. QKD has developed as a central technology for quantum networks, enabling to push further quantum communication technologies building blocks, as well quantum communication system design. At Quriosity, we have a long-term collaboration with the GTO team on experimental quantum communications and are particularly interested in continuous-variable quantum communications system design, its interplay with digital signal processing, with applications to multimode quantum communications.

Building a quantum processor that we could use to solve real-world problems with practical benefits might constitute one of the most burning scientific and technological challenges of the beginning of the 21st century. A central conviction underpinning QURIOSITY project is that quantum photonics combined with digital technologies will play a leading role in unveiling the power of high-dimensional controllable quantum systems, and transition towards the demonstration of a useful quantum advantage for information processing tasks. We investigate new theoretical questions related to quantum information processing (QIP) with high-dimensional photonic systems in close collaboration with leading experimental teams such as quantum frequency processor (in collaboration with Nadia Belabas, at C2N) and programmable linear circuits operating on a multimode fiber (in collaboration with Sylvain Gigan, at LKB).
