Probing locality and entanglement properties across the many-body spectrum using a superconducting processor

ORAL

Abstract

The spectrum and dynamics of strongly interacting particles can display properties of localization and entanglement that are challenging to simulate on a classical computer at a sufficiently large scale. In this work, we use a two-dimensional, 4x4 array of superconducting transmon qubits as a quantum emulator to explore locality and entanglement properties across the many-body spectrum of the strongly-interacting hard-core Bose-Hubbard model. We prepare non-thermal, coherent excited states and probe their many-body spectra using simultaneous high-fidelity control and readout. We discuss the potential for observing transitions between localized and delocalized many-body states in this system.
