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 paper reviews quantum spin squeezing, which characterizes the sensitivity of a state
with respect to SU (2) rotations, and is significant for both entanglement detection and high …

Squeezing of quantum fluctuations by means of entanglement is a well-recognized goal in
the field of quantum information science and precision measurements. In particular …

Probing the collective spin state of an ensemble of atoms may provide a means to reduce
heating via the photon recoil associated with the measurement and provide a robust …

We introduce a spin-squeezing technique that is a hybrid of two well-established spin-
squeezing techniques, quantum nondemolition measurement (QND), and one-axis twisting …

We analyze the creation of spin squeezed atomic ensembles by simultaneous dispersive
interactions with several optical frequencies. A judicious choice of optical parameters …

We present a theoretical investigation of coherent dynamics of a spin qubit encoded in
hyperfine sublevels of an alkali-metal atom in a far off-resonant optical dipole trap. The qubit …

We study the three-dimensional nature of the quantum interface between an ensemble of
cold, trapped atomic spins and a paraxial laser beam, coupled through a dispersive …

A majority of ultracold atom experiments utilize resonant absorption imaging techniques to
obtain the atomic density. To make well-controlled quantitative measurements, the optical …

We report on a novel experiment to generate non-classical atomic states via quantum non-
demolition (QND) measurements on cold atomic samples prepared in a high-finesse ring …
