Publikováno v: Physical Review Research, Vol 5, Iss 4, p 043054 (2023)

Due to numerous limitations including restrictive qubit topologies, short coherence times, and prohibitively high noise floors, few quantum chemistry experiments performed on existing noisy intermediate-scale quantum hardware have achieved the high b

Unitary partitioning and the contextual subspace variational quantum eigensolver

Autor: Alexis Ralli, Tim Weaving, Andrew Tranter, William M. Kirby, Peter J. Love, Peter V. Coveney

Publikováno v: Physical Review Research, Vol 5, Iss 1, p 013095 (2023)

The contextual subspace variational quantum eigensolver (CS-VQE) is a hybrid quantum-classical algorithm that approximates the ground-state energy of a given qubit Hamiltonian. It achieves this by separating the Hamiltonian into contextual and noncon

Implementation of measurement reduction for the variational quantum eigensolver

Autor: Alexis Ralli, Peter J. Love, Andrew Tranter, Peter V. Coveney

Publikováno v: Physical Review Research, Vol 3, Iss 3, p 033195 (2021)

One limitation of the variational quantum eigensolver algorithm is the large number of measurement steps required to estimate different terms in the Hamiltonian of interest. Unitary partitioning reduces this overhead by transforming the problem Hamil
