Improving Single Excitation Fidelity in Rydberg Superatoms for Efficient Single Photon Emission
Vidisha Aggarwal, Boxi Li, Eloisa Cuestas +4
Deterministic single photon emission from a Rydberg ensemble coupled to an optical cavity requires high-fidelity preparation of collective single excitations. In such a setup imper…
Imperfect blockade in Rydberg superatoms
Valentin Magro, Sébastien Garcia, Alexei Ourjoumtsev
Ensembles of atoms interacting via their Rydberg levels, known as "superatoms" for their ability to encode qubits and to emit single photons, attract increasing attention as buildi…
Protecting collective qubits from non-Markovian dephasing
Antoine Covolo, Valentin Magro, Mathieu Girard +2
Collectively-encoded qubits, involving ensembles of atomic or solid-state emitters, present many practical advantages for quantum technologies. However, they suffer from uncontroll…
Deterministic Free-Propagating Photonic Qubits with Negative Wigner Functions
Valentin Magro, Julien Vaneecloo, Sébastien Garcia +1
Engineering quantum states of free-propagating light is of paramount importance for quantum technologies. Coherent states ubiquitous in classical and quantum communications, squeez…
An Intracavity Rydberg Superatom for Optical Quantum Engineering: Coherent Control, Single-Shot Detection and Optical Phase Shift
Julien Vaneecloo, Sébastien Garcia, Alexei Ourjoumtsev
We demonstrate a new versatile building block for optical quantum technologies, based on an intracavity Rydberg-blockaded atomic ensemble acting as a single two-level superatom. We…
High-Resolution Imaging of Cold Atoms through a Multimode Fiber
Nicolas Vitrant, Sébastien Garcia, Kilian Müller +1
We developed an ultra-compact high-resolution imaging system for cold atoms. Its only in-vacuum element is a multimode optical fiber with a diameter of m, which simultaneou…
