Determining Ground-State Phase Diagrams on Quantum Computers via a Generalized Application of Adiabatic State Preparation

SYMMETRY-BASEL, 14(4).

By: A. Francis n, E. Zelleke*, Z. Zhang *, A. Kemper  n & J. Freericks *

author keywords: quantum phase transition; adiabatic evolution; quantum computing; XY model; super-conducting qubits
TL;DR: This work uses a local adiabatic ramp for state preparation to allow us to directly compute ground-state phase diagrams on a quantum computer via time evolution and is able to calculate an accurate phase diagram on both two- and three-site systems using IBM quantum machines.

2021 journal article

Many-body thermodynamics on quantum computers via partition function zeros

SCIENCE ADVANCES, 7(34).

By: A. Francis n, D. Zhu *, C. Alderete *, S. Johri*, X. Xiao n, J. Freericks *, C. Monroe *, N. Linke *, A. Kemper  n

TL;DR: This work shows how to find partition function zeros on noisy intermediate-scale trapped-ion quantum computers in a scalable manner, using the XXZ spin chain model as a prototype, and observes their transition from XY-like behavior to Ising-likebehavior as a function of the anisotropy.
