Analog-digital quantum simulation of a disorder-induced localized phase on a D-Wave Advantage2 QPU
Oral-In-person
Abstract
Novel techniques in modern quantum annealing processors enable new avenues of research. Combining
techniques like qubit excitation midway through an anneal, and readout of the qubit state in an
arbitrary basis, enables quantum simulation of dynamical physical systems and a path towards
analog-digital quantum computing: an exciting emerging computational paradigm that combines
aspects of analog Hamiltonian dynamics with digital control.
By leveraging these new capabilities, we present experimental realization of the expected dispersion
relation of a one-dimensional transverse-field Ising model in the absence of longitudinal bias on a
D-Wave Advantage2™ quantum processing unit (QPU), and subsequently demonstrate the onset of a
disorder-induced localization phase by introducing controlled randomness into the system. These
results affirm the D-Wave Advantage2 QPU as a rich platform for the simulation of
dynamical quantum systems.
