Scalable, self-verifying variational quantum eigensolver using adiabatic warm starts
Bojan ŽunkoviÄ, Marco Ballarin, Lewis Wright +1
We study an adiabatic variant of the variational quantum eigensolver (VQE) in which VQE is performed iteratively for a sequence of Hamiltonians along an adiabatic path. We derive t…

Quantum circuits for partial differential equations in Fourier space
Michael Lubasch, Yuta Kikuchi, Lewis Wright +1
For the solution of partial differential equations (PDEs), we show that the quantum Fourier transform (QFT) can enable the design of quantum circuits that are particularly simple,…

Noisy intermediate-scale quantum simulation of the one-dimensional wave equation
Lewis Wright, Conor Mc Keever, Jeremy T. First +5
We design and implement quantum circuits for the simulation of the one-dimensional wave equation on the Quantinuum H1-1 quantum computer. The circuit depth of our approach scales a…
