Fast spin squeezing by distance-selective long-range interactions with Rydberg molecule dressing (2022)
Journal Article

We propose a Rydberg molecule dressing scheme to create strong and long-ranged interactions at selective distances. This is achieved through laser coupling ground-state atoms off-resonantly to an attractive molecular curve of two interacting Rydberg...
