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 …

Atoms in high-lying Rydberg states with large values of the principal quantum number n, n⩾
300, form a valuable laboratory in which to explore the control and manipulation of quantum …

Quantum nondemolition (QND) measurement of collective variables by off-resonant optical
probing has the ability to create entanglement and squeezing in atomic ensembles. Until …

The electric fields near the heterogeneous metal-dielectric surface of an atom chip were
measured using cold atoms. The atomic sensitivity to electric fields was enhanced by …

We have used quantum control to suppress the impact of random atom positions on
coherent population transfer within atom pairs, enabling the observation of dipole-dipole …

Coherent superpositions of the 49 s 1/2 and 48 s 1/2 Rydberg states of cold 87 Rb atoms
were studied near the surface of an atom chip. The superpositions were created and …

A nonresonant microwave dressing field at 38.465 GHz was used to eliminate the static
electric dipole moment difference between the 49 s 1/2 and 48 s 1/2 Rydberg states of 87 Rb …

We present a fully analytical solution of the dynamics of two strongly driven atoms resonantly
coupled to a dissipative cavity field mode. We show that an initial atom-atom entanglement …

We examine the question of survival of quantum entanglement between the bipartite states
and multiparticle states like GHZ states under the action of a dephasing bath by the …

We demonstrate a novel time-domain method to probe electronic coherence in ensembles
of cold Rydberg atoms coupled via nearly resonant dipole-dipole interactions. Short laser …
