Quantum Measurements with Bose-Einstein condensates strongly coupled to nanophotonic structures
Quantum technologies have been recently recognized by the European Commission as a key resource for future applications in sensing, information processing, security and communications. In this context, this project aims at building quantum systems with a high degree of control and coherence, as an experimental resource to explore some of the abovementioned applications. As an elementary resource for quantum information, we are using ultracold neutral in optical traps. Along a first line, we are investigating how these atoms can be coupled to the field of nanophotonic structure with potential applications in sensing and metrology. Along a second closely related line, we have build a reconfigurable platform to create defect-free arrays of more than 50 individually-controlled atoms interacting through their Rydberg states, with potential applications in quantum simulations and information processing. Along a third line, we are studying chains of atoms strongly coupled to a fiber-based optical cavity. Conclusion of the action: the Rydberg atom array experiment turned out to be extremely successful at performing various tasks in quantum simulations, with up to 50 qubits and an unprecedented degree of fidelity, making it a very promising platform for future applications of the second quantum revolution.

Project objective
Most of the technologies at the heart of our information society, including the semiconductor and the laser, are based on the laws of quantum mechanics. Yet, there is still a lot to gain in harnessing quantum physics at the elementary level, for example to overcome the sensitivity limits in various kinds of measurements in the quantum regime. In this project, we plan to explore an emerging field of quantum technologies at the boundary between atomic physics and nanoscience, by studying the properties of Bose-Einstein condensates coupled to the evanescent field of nanophotonic structures. We will use this new light-matter interface to build a hybrid quantum gyroscope where the optical Sagnac effect in a photonic integrated circuit is enhanced by slow light in a Bose-Einstein condensate strongly coupled to it. The optical structures will be integrated on atom chips, for improved stability and scalability. Beyond the gyroscope itself, this work will create new prospects for combining the technological opportunities of nanophotonics with the very fruitful field of atomic physics, opening new avenues in quantum technologies, which are expected to become in the near future a key driver for the European competitiveness in information technology.
