Abstract[English]
A quantum memory device for storing a signal field is provided. The quantum memory device comprises an optical cavity comprising a first reflective surface and a second reflective surface; a first optical element and a second optical element arranged within the optical cavity; an atomic system situated between the first optical element and the second optical element, the atomic system configured to store the signal field via an atomic transition; and one or more magnets configured to apply an axial magnetic field across the atomic system.[French]
L'invention concerne un dispositif de mémoire quantique pour stocker un champ de signal. Le dispositif de mémoire quantique comprend une cavité optique comprenant une première surface réfléchissante et une seconde surface réfléchissante ; un premier élément optique et un second élément optique agencés à l'intérieur de la cavité optique ; un système atomique situé entre le premier élément optique et le second élément optique, le système atomique étant configuré pour stocker le champ de signal par l'intermédiaire d'une transition atomique ; et un ou plusieurs aimants configurés pour appliquer un champ magnétique axial à travers le système atomique.
