The Photonics and Quantum Information (QPI) team at the institute of Physics of Nice, INPHYNI (UMR 7010 CNRS/Uni. Côte d’Azur, Nice, France) is one of the world experts in quantum photonics.
The QPI team is active in the field of photonic quantum technologies, conducting research in both fundamental and applied quantum information and optics. This work notably involves the development of telecom-grade photonic systems designed to demonstrate quantum advantage in communication, on-fly computing and metrology. These systems, primarily based on integrated photonic circuits and on guided wave components, enable the exploitation of highly efficient nonlinear optical interactions as well as the active routing of information. This represents a major advantage for the engineering of on-demand configurable quantum states, whether in the discrete-variable, continuous-variable, or hybrid regimes.
Among its noticeable achievements, we find the integration on photonic chips for quantum relay and single- and multi-mode squeezing operation (on Silicon-based or with in-house circuits on lithium niobate), the distribution of entanglement, via spectral multiplexing, along optical fiber sections, the realization of a coherent wavelength interface, and a patented plug-&-play quantum network synchronization method. In addition, QPI has a strong knowledge in electronics dedicated to stabilizing laser sources and large interferometers, and for synchronizing optical reference signals of a few ps over several tens of km. QPI has also developed a fiber quantum communication testbed over the Côte d’Azur area, based on dark fibers, within a cooperation agreement settled with Orange (May 2019).
