Spontaneous parametric down-conversion (SPDC) is the most widely used process for generating photon pairs entangled in various degrees of freedom such as polarization, time-energy, position-transverse momentum, and angle-orbital angular momentum (OAM). In SPDC, a pump photon interacts with a non-linear optical crystal and splits into two entangled photons called the signal and the idler photons. The SPDC process has been studied extensively in the last few decades for various pump and crystal… 

Computational Study of Dynamic Susceptibility and Phase-Matching Angle by Two-Photon Entangled Generation.

Two-photon entangled generation is used to produce an entangled photon source which is a key and core element concerning the technology applications of quantum computing, quantum communication, and

Maximizing the validity of the Gaussian approximation for the biphoton state from parametric down-conversion

This work presents a choice of α which maximizes the validity of the Gaussian approximation and discusses the so-called super -Gaussian and cosine Gaussian approximations as practical alternatives with improved predictive power for experiments.

Bright correlated twin-beam generation and radiation shaping in high-gain parametric down-conversion with anisotropy.

This work provides a rigorous theoretical description of the spatial properties of bright squeezed light in the presence of strong anisotropy and investigates a single crystal and a system of two crystals with an air gap and demonstrates the generation of bright correlated twin-beams in such configurations at high gain due to an isotropy.

Simulation of a polarization-transverse momentum hyperentangled photon source

Abstract. The simulation and analysis of a hyperentangled photon source based on polarization and transverse momentum are achieved using the MATLAB platform. The analysis includes determining the

Analysis of the Spatial Properties of Correlated Photon in Collinear Phase-Matching

In this paper, the spatial properties of correlated photon in collinear phase-matching in the process of spontaneous parametric down conversion (SPDC) are researched. Based on the study of the

Multiple-Valued Logic Modelling for Agents Controlled via Optical Networks

Multiple-valued logic functions defined within discrete k-valued Allen–Givone algebra are proposed for the logically linked list of entries and the distributed ledger, which can be used for distant data verification and breakdown restoration in mobile agents with the help of partner network nodes.
