Use of two-photon light for absolute calibration of photoelectric detectors
TLDR
In this article, a method for calibrating photodetectors based on some characteristics of the statistics of the field of spontaneous parametric light scattering is described, and a phenomenological theory of parametric scattering is used to demonstrate that photons are only emitted in pairs.Abstract:
A description is given of a method for calibrating photodetectors based on some characteristics of the statistics of the field of spontaneous parametric light scattering. A phenomenological theory of parametric scattering is used to demonstrate that photons are only emitted in pairs. It is shown that, in principle, a priori information on the two-photon character and directionality of parametrically scattered light can be used for absolute calibration of photodetectors operated both in the analog linear regime and in the discrete photoelectron pulse counting regime.read more

TL;DR: In this paper, the authors present a loophole-free violation of local realism using entangled photon pairs, ensuring that all relevant events in their Bell test are spacelike separated by placing the parties far enough apart and by using fast random number generators and high-speed polarization measurements.

Photonic quantum information processing: A concise review
TL;DR: The photonic quantum computing represents an exciting path to medium and large-scale processing as mentioned in this paper, and the development of integrated platforms, improved sources and detectors, novel noise-tolerant theoretical approaches, and more have solidified it as a leading contender for both quantum information processing and quantum networking.

Photon Correlations in the Parametric Frequency Splitting of Light
TL;DR: In this paper, the correlation effects in parametric photon-pair production are studied within the framework of a physically realistic model, which takes into account the finite sizes of the target and the beam cross section, and allows for dispersion and anisotropy in the linear susceptibility.
