The exquisite properties of Rydberg levels make them particularly appealing for emerging quantum technologies. The lifetime of low-angular-momentum laser-accessible levels is however limited to a few 100μs by optical transitions and microwave blackb

We report on our recent experimental results that pave the way for the realization of quantum simulations with Circular Rydberg atoms: we present the preparation and laser-trapping of these states in an optical-access cryostat.

International audience; Rydberg atoms are remarkable tools for quantum simulation and computation. They are the focus of an intense experimental activity, mainly based on low-angular-momentum Rydberg states. Unfortunately, atomic motion and levels li

The main objective of quantum simulation is an in-depth understanding of many-body physics, which is important for fundamental issues (quantum phase transitions, transport, …) and for the development of innovative materials. Analytic approaches to

Cold-atom based implementation of the quantum Rabi model

Autor: A. Dareau, Philipp Schneeweiss, C. Sayrin

The interaction of a two-level system (TLS) with a single bosonic mode is one of the most fundamental processes in quantum optics. Microscopically, it is described by the quantum Rabi model (QRM). Here, we propose an implementation of this model base
