Frequency combs quantum metrology: FRECQUAM, Nicolas Treps

Nicolas Treps, professor and researcher at UPMC’s Kastler Brossel Laboratory, works on the study and manipulation of quantum properties of frequency combs, whether for metrology or quantum information. With the FRECQUAM project funded by the ERC, he proposed to reach and improve the sensitivity limits imposed by the quantum nature of the optical link in experiments such as positioning in space-time or measuring dispersing or speeds.


"This funding has allowed me to develop my own research activity, hire doctoral and post-doctoral students, and thus acquire a true scientific independence while protecting the activities of the entire group. This type of program enables us to focus on the heart of our business, in all its facets, and, beyond research so I could take responsibility for coordinating research, teaching and participate in UPMC governing bodies, "says Nicolas Treps. "This funding is therefore a real springboard for the future. The project must succeed and once the grant is finished it is difficult to sustain investment to continue the research.”

Nicolas Treps implemented stabilized laser sources and interferometric techniques which go beyond existing techniques. He also managed to show how to manipulate photons in frequency combs and implement a source of quantum frequency combs that will improve the sensitivity of measurements and also achieve the earliest experiments in parallelized processing quantum information.


His basic research funded by the ERC enabled him to achieve results on the optical fibers that led to the creation of a startup called CAILabs, which received the support from the SATT Lutech and has already obtained 1,000,000€ in seed money.
