Source-Independent Quantum Random Number Generation

open access: yesPhysical Review X, 2016
Quantum random number generators can provide genuine randomness by appealing to the fundamental principles of quantum mechanics. In general, a physical generator contains two parts—a randomness source and its readout.

Loss-tolerant measurement-device-independent quantum random number generation

open access: yesNew Journal of Physics, 2015
Quantum random number generators (QRNGs) output genuine random numbers based upon the uncertainty principle. A QRNG contains two parts in general—a randomness source and a readout detector.

Effective Number Theory: Counting the Identities of a Quantum State

open access: yesEntropy, 2020
Quantum physics frequently involves a need to count the states, subspaces, measurement outcomes, and other elements of quantum dynamics. However, with quantum mechanics assigning probabilities to such objects, it is often desirable to work with the ...

QUANTUM HAMILTONIANS AND PRIME NUMBERS [PDF]

open access: yesModern Physics Letters A, 2003
A short review of Schrödinger Hamiltonians for which the spectral problem has been related in the literature to the distribution of the prime numbers is presented here. We notice a possible connection between prime numbers and centrifugal inversions in black holes and suggest that this remarkable link could be directly studied within trapped Bose ...

Robust Quantum Search with Uncertain Number of Target States

open access: yesEntropy, 2021
The quantum search algorithm is one of the milestones of quantum algorithms. Compared with classical algorithms, it shows quadratic speed-up when searching marked states in an unsorted database. However, the success rates of quantum search algorithms are

Multi-bit quantum random number generation from a single qubit quantum walk

open access: yesScientific Reports, 2019
We present a scheme for multi-bit quantum random number generation using a single qubit discrete-time quantum walk in one-dimensional space. Irrespective of the initial state of the qubit, quantum interference and entanglement of particle with the ...
