Digital quantum simulation of many-body localization in quasiperiodic Floquet systems

ORAL

Abstract

Many-body localization (MBL) is a striking quantum phenomenon where strong disorder inhibits thermalization, causing energy eigenstates to remain localized and violate the eigenstate thermalization hypothesis.

In this work, we employ IBM’s Heron quantum processors to experimentally realize a kicked Ising model that serves as a Floquet many-body system exhibiting nonergodic dynamics under one- and two-dimensional quasiperiodic potentials.

We observe a robust MBL regime and an ergodic–MBL crossover on a one-dimensional lattice of 129 qubits and a two-dimensional lattice of 144 qubits.
