Digitized Counterdiabatic Quantum Algorithm for Protein Folding [PDF]
Physical Review Applied, 2022 We propose a hybrid classical-quantum digitized-counterdiabatic algorithm to tackle the protein folding problem on a tetrahedral lattice. Digitized-counterdiabatic quantum computing is a paradigm developed to compress quantum algorithms via the ...

A randomized quantum algorithm for statistical phase estimation [PDF]
Physical Review Letters, 2021 Phase estimation is a quantum algorithm for measuring the eigenvalues of a Hamiltonian. We propose and rigorously analyze a randomized phase estimation algorithm with two distinctive features. First, our algorithm has complexity independent of the number

Distributed quantum algorithm for Simon's problem [PDF]
Physical Review A, 2022 Limited by today’s physical devices, quantum circuits are usually noisy and difficult to be designed deeply. The novel computing architecture of distributed quantum computing is expected to reduce the noise and depth of quantum circuits.

Quantum algorithm for persistent Betti numbers and topological data analysis [PDF]
Quantum, 2021 Topological data analysis (TDA) is an emergent field of data analysis. The critical step of TDA is computing the persistent Betti numbers. Existing classical algorithms for TDA are limited if we want to learn from high-dimensional topological features ...

Quantum algorithm for the Navier–Stokes equations by using the streamfunction-vorticity formulation and the lattice Boltzmann method [PDF]
International Journal of Quantum Information, 2021 In this paper, a new algorithm for solving the Navier–Stokes equations (NSE) on a quantum device is presented. For the fluid flow equations, the stream function-vorticity formulation is adopted, while the lattice Boltzmann method (LBM) is utilized for ...

Exploiting Dynamic Quantum Circuits in a Quantum Algorithm with Superconducting Qubits. [PDF]
Physical Review Letters, 2021 To date, quantum computation on real, physical devices has largely been limited to simple, time-ordered sequences of unitary operations followed by a final projective measurement. As hardware platforms for quantum computing continue to mature in size and

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 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(-->).
