A few decades ago, quantum optics stood out as a new domain of physics by exhibiting
states of light with no classical equivalent. The first investigations concerned single photons …

We present a method of photon orbital angular momentum selection at very low light levels
using spatial interference between a strong local oscillator field and a weak beam. By using …

We have measured the joint Q-function of a highly multimode field using unbalanced
heterodyne detection with a charge-coupled device array detector. We use spectral …

We review experimental work on the measurement of the quantum state of optical fields, and
the relevant theoretical background. The basic technique of optical homodyne tomography …

We demonstrate that it is possible to choose an optimal signal mode for state reconstruction
when performing quantum-state tomography with array detectors. The mode optimization is …

A simple scheme for conditional generation of nonclassical light with sub-Poissonian photon-
number statistics is proposed. The method utilizes entanglement of signal and idler modes …

We present four models for describing a 3-D vision. Similar to the mirror scenario, our
models allow 3-D vision with no need for additional accessories such as stereoscopic …

Quantum information can be transferred from a beam of light to a cloud of atoms and
controllably released at a later time. This process forms the basis of many important …

We measure the joint Q function of a multispatial-mode field using a charge-coupled device
array detector in an unbalanced heterodyne configuration. The intensity pattern formed by …

Multiple scattering is a very common phenomenon since it occurs any time a wave meets a
disordered medium. As almost any natural object has random structure in one form or …
