“…If we only observe the scattered photons with large frequency shifts, this interaction is mostly between the input photons and the vacuum noise phonon fluctuations instead of interactions with the thermal phonon field. The quantum randomness from phonon vacuum fluctuations is the principle behind the QRNG of (Collins et al, 2015(Collins et al, , 2014 where a strong pump inside a highly nonlinear As 2 S 3 fiber generates spontaneous Raman photons in different frequency bands. The pump photons interact with phonons of different energies.…”

“…The scattered photons occupy the spectrum following a known probability distribution with two separate regions. One part of the spectrum is associated to thermal phonons and, in a time T , it has an expected scattered photon detection rate (Collins et al, 2015;Kobliska and Solin, 1973;Lin et al, 2007) R(ν, T ) = Cη∆νP L(1 + n BE (ν, T ))g(ν)…”

Random numbers are a fundamental resource in science and engineering with important applications in simulation and cryptography. The inherent randomness at the core of quantum mechanics makes quantum systems a perfect source of entropy. Quantum random number generation is one of the most mature quantum technologies with many alternative generation methods. We discuss the different technologies in quantum random number generation from the early devices based on radioactive decay to the multiple ways to use the quantum states of light to gather entropy from a quantum origin. We also discuss randomness extraction and amplification and the notable possibility of generating trusted random numbers even with untrusted hardware using device independent generation protocols.

Quantum key distribution (QKD) can ensure information security between two remote parties. To commercialise QKD technology successfully, it should be integrated with dense wavelength division multiplexing optical transport. However, various challenges limit the QKD's performance in terms of the quantum key rate, quantum bit error rates, and maximum achievable distance. In this study, the authors discuss some of the major practical limiting factors for QKD performance such as spontaneous Raman scattering, four-wave mixing, and amplified spontaneous emission.

“…Optical systems based on quantum properties of photons are particularly popular due to the ease with which photons can be produced, manipulated, and measured [6]. There are many different types of such optical QRNGs, distinguished by the particular kind of physical principle and measurement exploited in the generation of bits, such as branching paths [8], photonnumber statistics [9,10], time-of-arrival statistics [11,12], vacuum fluctuations [13][14][15], and Raman scattering [16]. Systems based on the detection of single photons have shown especially high bit rates and efficiencies [8][9][10][11][12].…”

Parity-based, bias-free optical quantum random number generation with min-entropy estimation

et al. 2020

We describe the generation of sequences of random bits from the parity of photon counts produced by polarization measurements on a polarization-entangled state. The resulting sequences are bias free, pass the applicable tests in the NIST battery of statistical randomness tests, and are shown to be Borel normal, without the need for experimental calibration stages or postprocessing of the output. Because the photon counts are produced in the course of a measurement of the violation of the Clauser-Horne-Shimony-Holt inequality, we are able to concurrently verify the nonclassical nature of the photon statistics and estimate a lower bound on the min-entropy of the bit-generating source. The rate of bit production in our experiment is around 13 bits/s.
