The "Transitions" International Research Center focuses on interdisciplinary efforts to tackle complex global challenges. Spanning fields like humanities, biology, oceanography, quantum technologies, environmental science, and computational methodologies, the goal is to foster significant scientific breakthroughs and prepare a new generation of scientific leaders. The center's structure i…
This thematic project aims to establish the conceptual bases and training of human resources necessary for the development of Second Generation Quantum Technologies by structuring a value-proposition to the market of industrial and service companies worldwide.Second Generation Quantum Technologies comprise solutions that directly benefit from quantum states of light or matter, such as sup…
In this proposal we shall continue our efforts to generate cutting-edge science where fundamental and applied research will advance together in the field of optics. Our research program comprises three main thrusts: cold-matter physics, plasmonics and biophotonics, fields that linked by a common theme of light matter interaction. In parallel we shall advance fundamental understanding and …
Dense atomic clouds represent an interesting platform for studying collective effects, such as super- and subradiance. On the other hand, the correlated emission and absorption of entangled photons has important applications in quantum technologies, in particular, quantum communication protocols. Generally, twin photons are emitted (or absorbed) by single atoms exploiting an atomic multil…
In this project, we will investigate the role of dimensionality and polarization in the scattering of light by point particles. The panel of skills of the participants makes it possible to study light scattering in 10 (optical cavity of Prof. Courteille), 20 (plasmonic structures of Prof. Guimarães) and 3D (magneto-optical traps of Prof. Kaiser). The dimensionality of the system is a crit…
This proposal aims at turning quantum sensor technology into reality. Ahead of the anticipated quantum revolution in commercial applications, the proposal will set up a research consortium working on two specific areas of research: (i) Analysis and implementation of new ideas for quantum sensors based on cold atoms interacting with optical cavities and investigations for the first dual-us…

This master's project aims to study the scattering of light by a dense sample of cold strontium atoms. Specifically, this project aims to implement a measurement of the electric field of light transmitted through a dense and disordered atomic sample. The measurement of the electric field will extend the regime of parameters for which we can characterize the true optical density of the clo…
Quantum gases experiments offers an unique platform where its properties (number of atoms, temperature, shape of the atomic density, interaction between particules, etc.) can be precisely tuned. In particular, the system dimensionality could be modelled making it possible to study physcial phenomena related to one- (1D) and two-dimensional (2D) systems. In the former, effective 2D systems…
Cold atoms represent an ideal platform for the implementation of second-generation quantum technologies. Particularly interesting opportunities emerge from a coherent coupling of the atoms to a single-mode light field enabled by a resonant optical cavity. This project will pursue two research lines. The first one is a study of the interaction of ultracold atoms with a ring cavity in param…

Today's most accurate inertial sensors are based on atomic interferometry. The objective of this project is to study, theoretically and experimentally, schemes of collective interaction between cold atoms and light in optical cavities in view of creating non-trivial collective spin states. We will investigate the potential of weakly entangled spin-squeezed states for improved quantum sens…
The thematic project addresses the construction of a sensor that can simultaneously be used as a standard for optical frequencies and gravimetry. Conventional standards consist in a laser oscillator locked to an ultra-stable optical cavity through a fast electronic servo using the Pound-Drever-Hall technique, which offers a good short-term stability. The accuracy and reproducibility of th…
Gravity sensors are indispensable devices for numerous applications in industry as well as in fundamental research. A particularly attractive technique translates the force of gravitational acceleration in a frequency measurement of Bloch oscillations of laser-cooled atoms confined in a stationary vertical light wave. In modern gravimeters oscillations are measured via the state of the at…

Non-classical light sources, such as single photons and entangled photon pairs, are essential for quantum computing, secure quantum communication, and precision metrology. Traditional methods, while effective, often fail to produce light with the spectral properties needed for integration with systems like quantum memories. Recent breakthroughs have shown that atomic ensembles can generat…
The objective of this research project is to study the eminent role that optical cavities can play in the emergence of collective effects and quantum correlations in atomic many-body systems. Superradiant enhancement of the decay of ultranarrow clock transitions in atoms resonantly driven inside optical cavities will provide next generation atomic clocks with orders of magnitude higher pr…
