Barren-plateau free variational quantum simulation of Z2 lattice gauge theories
Fariha Azad, Matteo Inajetovic, Stefan Kühn +1
In this work, we design a variational quantum eigensolver (VQE) suitable for investigating ground states and static string breaking in a lattice gauge theory (LGT).…

Fully optimised variational simulation of a dynamical quantum phase transition on a trapped-ion quantum computer
Lesley Gover, Vinul Wimalaweera, Fariha Azad +3
We time-evolve a translationally invariant quantum state on the Quantinuum H1-1 trapped-ion quantum processor, studying the dynamical quantum phase transition of the transverse fie…

Phase Transitions in the Classical Simulability of Open Quantum Systems
F. Azad, A. Hallam, J. Morley +1
We study the evolution of an open quantum system using a Langevin unravelling of the density matrix evolution over matrix product states. As the strength of coupling to and tempera…
