TL;DR: A technique for manipulating quantum information stored in collective states of mesoscopic ensembles by optical excitation into states with strong dipole-dipole interactions that can be employed for controlled generation of collective atomic spin states as well as nonclassical photonic states and for scalable quantum logic gates is described.

TL;DR: Several schemes for implementing a fast two-qubit quantum gate for neutral atoms with the gate operation time much faster than the time scales associated with the external motion of the atoms in the trapping potential are proposed.

TL;DR: In the laser excitation of ultracold atoms to Rydberg states, a dramatic suppression caused by van der Waals interactions is observed; the dependences of this suppression on both laser irradiance and atomic density are in good agreement with a mean-field model.

TL;DR: In this article, the long-range interaction potential curves of highly excited Rydberg atom pairs for the combinations Li, Li, Na-Na, K-K, Rb-Rb and Cs-Cs in a perturbative approach were calculated.

TL;DR: In this paper, the authors show how ultracold polar molecules, suggested as a new platform for quantum computation, can be manipulated to switch ''on'' and ''off'' their strong dipole-dipole interactions.
