A Study of Gate-Based and Boson Sampling Quantum Random Number Generation on IBM and Xanadu Quantum Devices

arXiv.org
Quantum mechanics offers a fundamentally unpredictable entropy source due to the intrinsic probabilistic nature of quantum measurements, making it attractive for secure random number generation.

Pseudothermal Light Based Quantum Random Number Generator

2020 4th International Symposium on Multidisciplinary Studies and Innovative Technologies (ISMSIT), 2020
The importance of quantum random number generators (QRNGs) is increasing day by day. An important aspect of any QRNG is the speed of the system. This paper introduces the theory behind a pseudothermal light based QRNG. This pseudothermal effect is provided by using an optical scatterer in the setup.

Efficient Randomness Extraction in Quantum Random Number Generators

Anais do II Workshop de Comunicação e Computação Quântica (WQuantum 2022), 2022
Randomness extraction algorithms play an essential role in Quantum Random Number Generators (QRNGs), where they are used to suppress unwanted classical noise and distill true randomness from their biased output. By employing the SHA-512 hash function and Toeplitz matrix multiplication, we analyse two suitable constructions based on different principles

Random Number Generation with Quantum Computers

Frontiers in Optics + Laser Science 2022 (FIO, LS), 2022
Random numbers feature in most cryptographic protocols, including those securing internet traffic. Most random number generators deployed on internet appliances are subject to cryptanalytic attack. We explore generating random numbers on compact quantum computers.

Source-Independent Quantum Random Number Generation with Partially Free Sources

2025 2nd International Symposium on AI and Cybersecurity (ISAICS)
Random number generation is vital for cryptography. The classical world faces inherent limitations in generating provably true random numbers. Quantum mechanics, however, provides a natural foundation for genuinely unpredictable outcomes.

Quantum random number generator vs. random number generator

2016 International Conference on Communications (COMM), 2016
A random number generator produces a periodic sequence of numbers on a computer. The starting point can be random, but after it is chosen, everything else is deterministic.

High-dimensional quantum random number generation by metalens array

Microoptics Conference
The technique of Quantum Random Number Generation (QRNG) is widely recognized as a superior method for generating true random numbers. This is due to the inherent security benefits offered by quantum effects.

Photonic ternary quantum random number generators

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2023
We construct a class of three-dimensional photonic quantum random number generators (QRNGs) and prove that each of them generates maximally unpredictable digits via measurements that are robust to errors. This shows that every sequence generated is strongly incomputable; hence its quality is provably better than that of every pseudo-random sequence ...

Quantum Random Number Generation within Idle Time Windows of Quantum Key Distribution

National Radio Science Conference
We present a quantum random number generator system that relies on precise time measurements of the intervals between random clicks of single photon detectors. These SPDs are embedded in a quantum key distribution system.
