Experimental study on the quantum search algorithm over structured datasets using IBMQ experience
Journal of King Saud University: Computer and Information Sciences, 2022 In this work, a quantum search algorithm over structured datasets is proposed. Subsequently, the algorithm is executed on a real chip quantum computer developed by IBM Quantum experience (IBMQ). QISKit, the software platform developed by IBM, is used for

Quantum Linear System Algorithm for General Matrices in System Identification
Entropy, 2022 Solving linear systems of equations is one of the most common and basic problems in classical identification systems. Given a coefficient matrix A and a vector b, the ultimate task is to find the solution x such that Ax=b.

Quantum algorithm for linear systems of equations. [PDF]
Physical Review Letters, 2008 Solving linear systems of equations is a common problem that arises both on its own and as a subroutine in more complex problems: given a matrix A and a vector b(-->), find a vector x(-->) such that Ax(-->) = b(-->).

Quantum algorithm for Feynman loop integrals [PDF]
Journal of High Energy Physics, 2021 We present a novel benchmark application of a quantum algorithm to Feynman loop integrals. The two on-shell states of a Feynman propagator are identified with the two states of a qubit and a quantum algorithm is used to unfold the causal singular ...

A quantum–quantum Metropolis algorithm [PDF]
Proceedings of the National Academy of Sciences, 2012 The classical Metropolis sampling method is a cornerstone of many statistical modeling applications that range from physics, chemistry, and biology to economics. This method is particularly suitable for sampling the thermal distributions of classical systems. The challenge of extending this method to the simulation of arbitrary quantum systems is that,

Quantum Algorithm for Time-Dependent Hamiltonian Simulation by Permutation Expansion [PDF]
PRX Quantum, 2021 We present a quantum algorithm for the dynamical simulation of time-dependent Hamiltonians. Our method involves expanding the interaction-picture Hamiltonian as a sum of generalized permutations, which leads to an integral-free Dyson series of the time ...
