We study the quasiprobability representation of quantum light, as introduced by Glauber and
Sudarshan, for the unified characterization of quantum phenomena. We begin with …

We present a general method to detect nonclassical radiation fields with systems of on-off
detectors. We especially study higher order correlations for the identification of nonclassical …

We study the properties of the cumulants of multimode boson operators and introduce the
phase-averaged quadrature cumulants as the measure of the non-Gaussianity of multimode …

We propose a quantum optical device to experimentally realize quantum processes, which
perform the regularization of the—in general highly singular—Glauber–Sudarshan P …

The phase-space quasiprobability distribution formalism for representing quantum states
provides practical tools for various applications in quantum optics such as identifying the …

Moments are expectation values of products of powers of position and momentum, taken
over quantum states (or averages over a set of classical particles). For free particles, the …
