Grand Unification of Quantum Algorithms

open access: yesPRX Quantum, 2021
Quantum algorithms offer significant speed-ups over their classical counterparts for a variety of problems. The strongest arguments for this advantage are borne by algorithms for quantum search, quantum phase estimation, and Hamiltonian simulation, which

Quantum Genetic Algorithms for Computer Scientists

open access: yesComputers, 2016
Genetic algorithms (GAs) are a class of evolutionary algorithms inspired by Darwinian natural selection. They are popular heuristic optimisation methods based on simulated genetic mechanisms, i.e., mutation, crossover, etc.

Quantum simulation of exact electron dynamics can be more efficient than classical mean-field methods

open access: yesNature Communications, 2023
Quantum algorithms for simulating electronic ground states are slower than popular classical mean-field algorithms such as Hartree–Fock and density functional theory but offer higher accuracy.

Continued Fractions and Probability Estimations in Shor’s Algorithm: A Detailed and Self-Contained Treatise

open access: yesAppliedMath, 2022
Shor’s algorithm for prime factorization is a hybrid algorithm consisting of a quantum part and a classical part. The main focus of the classical part is a continued fraction analysis.

Quantum security and theory of decoherence

open access: yesNew Journal of Physics, 2022
We sketch a relation between two crucial, yet independent, fields in quantum information research, viz. quantum decoherence and quantum cryptography. We investigate here how the standard cryptographic assumption of shielded laboratory, stating that data ...
