Rydberg atoms with principal quantum number n⪢ 1 have exaggerated atomic properties
including dipole-dipole interactions that scale as n 4 and radiative lifetimes that scale as n 3 …

Atom-based measurements of length, time, gravity, inertial forces and electromagnetic fields
are receiving increasing attention. Atoms possess properties that suggest clear advantages …

Controlling the quantum entanglement between parts of a many-body system is key to
unlocking the power of quantum technologies such as quantum computation, high-precision …

Atom-based standards for length and time as well as other physical quantities such as
magnetic fields show clear advantages by enabling stable and uniform measurements. Here …

By mapping the strong interaction between Rydberg excitations in ultra-cold atomic
ensembles onto single photons via electromagnetically induced transparency, it is now …

The strong interaction between individual Rydberg atoms provides a powerful tool exploited
in an ever-growing range of applications in quantum information science, quantum …

We review here the studies performed about interactions in an assembly of cold Rydberg
atoms. We focus especially on the review of the dipole–dipole interactions and on the effect …

We examine interactions between atoms continuously and coherently driven between the
ground state and a Rydberg state, producing “Rydberg-dressed atoms.” Because of the …

The coherent control of mesoscopic ensembles of atoms and Rydberg atom blockade are
the basis for proposed quantum devices such as integrable gates and single-photon …

The observation of strongly interacting many-body phenomena in atomic gases typically
requires ultracold samples. Here we show that the strong interaction potentials between …
