Recent decades have witnessed great developments in the field of quantum simulation—
where synthetic systems are built and studied to gain insight into complicated, many-body …

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 …

This review summarizes experimental works performed over the last decade by several
groups on the manipulation of a few individual interacting Rydberg atoms. These studies …

We present the first demonstration of a cnot gate between two individually addressed neutral
atoms. Our implementation of the cnot uses Rydberg blockade interactions between neutral …

Blockade interactions whereby a single particle prevents the flow or excitation of other
particles provide a mechanism for control of quantum states, including entanglement of two …

The realization of strong nonlinear interactions between individual light quanta (photons) is
a long-standing goal in optical science and engineering,, being of both fundamental and …

We study experimentally various physical limitations and technical imperfections that lead to
damping and finite contrast of optically driven Rabi oscillations between ground and …

Rydberg atoms have an electron in a state with a very high principal quantum number, and
as a result can exhibit unusually long-range interactions. One example is the bonding of two …

We report the direct measurement of the van der Waals interaction between two isolated,
single Rydberg atoms separated by a controlled distance of a few micrometers. Working in a …

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 …
