Enhancing Extractable Quantum Entropy in Vacuum-Based Quantum Random Number Generator [PDF]
Entropy, 2018 Information-theoretically provable unique true random numbers, which cannot be correlated or controlled by an attacker, can be generated based on quantum measurement of vacuum state and universal-hashing randomness extraction.

Source-device-independent heterodyne-based quantum random number generator at 17 Gbps [PDF]
Nature Communications, 2018 For many applications, quantum random number generation should be fast and independent from assumptions on the apparatus. Here, the authors devise and implement an approach which assumes a trusted detector but not a trusted source, and allows random bit ...

Homodyne-based quantum random number generator at 2.9 Gbps secure against quantum side-information [PDF]
Nature Communications, 2021 Security analyses for trusted quantum random number generators usually consider only classical side-information. Here, the authors fill this gap by fully characterising the experimental apparatus of a homodyne-based QRNG, assuming that the vacuum ...

Multiplexed Quantum Random Number Generation [PDF]
Quantum, 2019 Fast secure random number generation is essential for high-speed encrypted communication, and is the backbone of information security. Generation of truly random numbers depends on the intrinsic randomness of the process used and is usually limited by ...

A simple low-latency real-time certifiable quantum random number generator [PDF]
Nature Communications, 2021 In quantum random number generation, one has generally to choose between high speed and strong security. Here, the authors show how to bound several adversarial imperfections on state preparation and measurement, generating 8192 secure random bits every ...

Optical Quantum Random Number Generator [PDF]
Journal of Modern Optics, 1999 A physical random number generator based on the intrinsic randomness of quantum mechanics is described. The random events are realized by the choice of single photons between the two outputs of a beamsplitter.

A Gaussian-Distributed Quantum Random Number Generator Using Vacuum Shot Noise [PDF]
Entropy, 2020 Among all the methods of extracting randomness, quantum random number generators are promising for their genuine randomness. However, existing quantum random number generator schemes aim at generating sequences with a uniform distribution, which may not ...

Binary quantum random number generator based on value indefinite observables [PDF]
Scientific ReportsAll quantum random number generators based on measuring value indefinite observables are at least three-dimensional because the Kochen–Specker Theorem and the Located Kochen–Specker Theorem are false in dimension two.
