This paper reviews recent efforts to realize a high‐efficiency memory for optical pulses using
slow and stored light based on electromagnetically induced transparency (EIT) in …

We investigate how the entanglement properties of a two-mode state can be improved by
performing a coherent superposition operation t â+ r ↠of photon subtraction and …

We present a theoretical and experimental study of the ultranarrow bandwidth Faraday
anomalous dispersion optical filter operating at the rubidium D_1 line (795 nm). This atomic …

We report the demonstration of a magnetometer with noise-floor reduction below the shot-
noise level. This magnetometer, based on a nonlinear magneto-optical rotation effect, is …

We present experimental results on the generation of multi-spatial-mode, single-beam,
quadrature squeezed light using four-wave mixing in hot Rb vapor. Squeezing and phase …

We have studied relative-intensity fluctuations for a variable set of orthogonal elliptic
polarization components of a linearly polarized laser beam traversing a resonant 87 Rb …

Squeezed states of light have found their way into a number of applications in quantum-
enhanced metrology due to their reduced noise properties. In order to extend such an …

We investigated the spatial distribution of quantum fluctuations in a squeezed vacuum field,
generated via polarization self-rotation (PSR) interaction of an ensemble of Rb atoms and a …

We demonstrate an experimental technique for the quantum-state tomography of the
collective qutrit states of a room-temperature alkali-metal vapor. It is based on the …

We present a technique for squeezed light detection based on direct imaging of the
displaced-squeezed-vacuum state using a CCD camera. We show that the squeezing …
