This Colloquium examines the field of the Einstein, Podolsky, and Rosen (EPR) gedanken
experiment, from the original paper of Einstein, Podolsky, and Rosen, through to modern …

The quantum statistical properties of radiation represent an important branch of modern
physics with rapidly increasing applications in spectroscopy, quantum generators of …

Quantum frequency conversion, a process with which an input beam of light can be
converted into an output beam of a different frequency while preserving the quantum state, is …

A pulsed, balanced homodyne detector has been developed for precise measurement of the
electric field quadratures of pulsed optical quantum states. A high level of common mode …

We report an experimental quantum key distribution that utilizes pulsed homodyne
detection, instead of photon counting, to detect weak pulses of coherent light. Although our …

Abstract The Einstein-Podolsky-Rosen (EPR) paradox is demonstrated experimentally for
continuous variables by employing a nondegenerate optical parametric amplifier (NOPA) …

A local oscillator (LO) which can correctly decode the spatiotemporally distorted quadrature-
squeezed light generated by means of single-pass traveling-wave optical parametric …

Using ultrashort laser pulses, we have observed quadrature squeezing and parametric gain
in quasi-phase-matched KTiOPO_4 waveguides. Using a local oscillator pulse that is 2.5 …

Following recent progress in the experimental application of electro-optic sampling to the
detection of the quantum fluctuations of the electromagnetic-field ground state and …

We investigate temporal effects in pulsed squeezing by parametric amplification, including
effects of group-velocity dispersion. Our calculations show that the local oscillator pulse …
