“…The importance of the generation of polarization EPs and multipartite photon correlations by FWM as a function of the parameter space was highlighted by Petrov et al in 2017 [58]. They showed that controlling parameters such as the nonlinearity, pump power, and bandwidth measurement filtering creates different regimes that can satisfy important quantum optical applications.…”

The latest breakthroughs in quantum technologies, such as satellite quantum communications, present new challenges, imposing stringent restrictions on weight, size, and power consumption of quantum information systems. Here, we show that nonlinear and quantum optics provides powerful resources to confront these challenges by offering attractive solutions for photon-pair counting and quantum-entanglement detection. We demonstrate a low-cost, readily miniaturizable photon-pair counting module, which consumes less than 100 μAh during a sub-10 ms power-on/off measurement cycle, thus providing a meaningful performance as a promising component for satellite quantum technologies.

“…A dichroic mirror (DM in figure 1) then separates the signal and idler fields, sending them into two detection channels. Each of these fields then passes through additional narrowband bandpass filters (BPF1 and BPF2) for a higher coincidence-to-accidental ratio of photon-pair detection [18].…”

Quantum random numbers from a fiber-optic photon-pair source

Sources of random numbers are critical for a broad range of applications, spanning from gaming to random-samplingbased analysis and secure communications [1]. Optical technologies offer a vast arsenal of tools for the generation of random numbers at high speeds and in convenient formats [2][3][4][5][6][7][8]. Of particular interest are the optical methods in which random numbers are generated as a result of quantum processes [1,[9][10][11][12][13]. Although the evolution of quantum systems is governed by deterministic equations, a measurement on quantum observables can yield, unlike classical processes, truly unpredictable outcomes, suggesting a powerful resource for a broad range of random-number applications and providing a unique platform for in-depth studies into the fundamental aspects of randomness [1,13].Beam splitting of single-photon fields stands out as perhaps the most celebrated example of quantum optical random number generation (RNG). Invaluable for thought experiments and methodological arguments, this method is, however, difficult to integrate into information networks. Promising networkingcompatible quantum optical RNG approaches demonstrated within the past few years include RNG schemes based on laser noise [2, 3], weak photonic coherent states [4,5], stimulated Raman scattering [6], as well as optical parametric processes in crystals with quadratic nonlinearity [7] and semiconductor Laser Physics Letters
