Analog-digital quantum simulation of a disorder-induced localized phase on a D-Wave Advantage2 QPU

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.
