High-Speed and Scalable Quantum Random Number Generation Using InGaN Micro-LEDs

IEEE Photonics Journal
This paper presents a high-speed and scalable quantum random number generator (QRNG) based on InGaN micro-LED arrays. While traditional QRNG systems face limitations in data rate and integration complexity, our approach leverages the intrinsic quantum ...

Quantum Random Numbers Generated by a Cloud Superconducting Quantum Computer [PDF]

, 2020
AbstractA cloud quantum computer is similar to a random number generator in that its physical mechanism is inaccessible to its users. In this respect, a cloud quantum computer is a black box. In both devices, its users decide the device condition from the output. A framework to achieve this exists in the field of random number generation in the form of

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics

Advanced Functional Materials, EarlyView.
2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

A simple low-latency real-time certifiable quantum random number generator

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 ...

High speed self-testing quantum random number generation without detection loophole

, 2017
Quantum mechanics provides means of generating genuine randomness that is impossible with deterministic classical processes. Remarkably, the unpredictability of randomness can be certified in a self-testing manner that is independent of implementation ...

Novel pseudo-random number generator based on quantum random walks [PDF]

Scientific Reports, 2016
AbstractIn this paper, we investigate the potential application of quantum computation for constructing pseudo-random number generators (PRNGs) and further construct a novel PRNG based on quantum random walks (QRWs), a famous quantum computation model. The PRNG merely relies on the equations used in the QRWs and thus the generation algorithm is simple ...

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

Advanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

Clauser-Horne Bell test with imperfect random inputs

, 2015
Bell test is one of the most important tools in quantum information science. On the one hand, it enables fundamental test for the physics laws of nature, and on the other hand, it can be also applied in varieties of device independent tasks such as ...

Color Routing and Beam Steering of Single‐Molecule Emission with a Spherical Silicon Nanoantenna

Advanced Functional Materials, EarlyView.
We experimentally demonstrate broadband directional emission from single molecules using a single spherical silicon nanoparticle assembled via DNA origami. By varying nanoparticle (NP) size and emitter position, we achieve unidirectional emission, beam steering, and color routing at the nanoscale, revealing modal interference as the underlying ...
