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…
