My Ph.D. in Atomic Physics, realized at the Observatoire de Paris – SYRTE (SYstème de Référence Temps Espace, the french frequency – time laboratory), on the cold atom gravimeter and my working experience in Florence on the Space Atom Interferometer (SAI) project of the European Space Agency (ESA) have allowed me to master atom interferometry physics. My Ph.D thesis describes the development of the new absolute atomic gravimeter and presents the major advances that it has made possible in terms of accuracy and sensitivity. We have also invented new gravimeter concepts turned to geophysics or space inertial sensors. In Florence, I have taken charge of the Space Atom Interferometer (SAI) project developed under the contract of the European Space Agency. The final purpose of this prototype is to validate technologies in order to send an atom interferometer in the International Space Station (ISS). In Stockholm, I have changed research topic to focus on quantum information, working on the experiment QUASIRIO. Trapped Rydberg ions are a promising new system for quantum information processing. First, we have studied the interaction of an ion excited to Rydberg state with the trapping quadrupole field. Second, we have demonstrated a two-photons oscillation from the fundamental state to the Rydberg state through STIRAP (STImulated Raman Adiabatic Passage) with Ultraviolet photons. This demonstrates the feasibility of a quantum phase-gate. It is a key achievement towards a quantum computer.

Research towards a large-scale, fault tolerant quantum computer using a modular, building block architecture for plug-and-play scalability. Qubit based on the physics of on-chip trapped-ions, using microwave-driven quantum logic operations. Associate tutor in Quantum Mechanics, responsible for running student workshops and problem classes, marking/assessing student coursework.
The project Quasirio (Quantum simulation with Rydberg trapped ions) focuses on the realization and application of trapped Rydberg ions for quantum information processing and quantum simulation. It will bring together two prospective quantum computational systems: trapped ions and Rydberg atoms. Joining them will form a novel quantum system with advantages from both sides. This approach will open a new path of investigation for quantum computing and simulation and will allow investigation of different physical qualities not yet addressed in the existing systems.
