The theory of the beam splitter (BS) in quantum optics is well developed and based on fairly simple mathematical and physical foundations. This theory has been developed for any type of BS and is based on the constancy of the reflection coefficients R ...

Evaluation of the Electron Contamination in Photon Therapy Using BEAMnrc Code
Background: Today, high-energy photon beams are widely used in the treatment of all types of cancers. However, the production of electrons as contaminants in the photon pathway provides the necessity for research in this field.

Quantum Theory of Scattering of Nonclassical Fields by Free Electrons
At present, there is no non-perturbative theory of scattering of nonclassical electromagnetic waves by free electrons that describes the scattering process completely with the help of quantum physics.

Experimental position-time entanglement with degenerate single photons
We report an experiment in which two-photon interference occurs between degenerate single photons that never meet. The two photons travel in opposite directions through our fibre-optic interferometer and interference occurs when the photons reach two ...

Hertz potentials approach to the dynamical Casimir effect in cylindrical cavities of arbitrary section [PDF]
We study the creation of photons in resonant cylindrical cavities with time dependent length. The physical degrees of freedom of the electromagnetic field are described using Hertz potentials. We describe the general formalism for cavities with arbitrary

Spatial entanglement of paired photons generated in cold atomic ensembles
Cold atomic ensembles can mediate the generation of entanglement between pairs of photons. Photons with specific directions of propagation are detected, and the entanglement can reside in any of the degrees of freedom that describe the whole quantum ...

Semiconductor quantum dot - a quantum light source of multicolor photons with tunable statistics [PDF]
We investigate the intensity correlation properties of single photons emitted from an optically excited single semiconductor quantum dot. The second order temporal coherence function of the photons emitted at various wavelengths is measured as a function

Since the seminal work by Ginsburg, et al. (1984), the subject of giving the Next Linear Collider photon-photon capability, as well as electron-positron capability, has drawn much attention. A 1990 article by V.I. Telnov describes the situation at that time. In March 1994, the first workshop on this subject was held.
