abstract = {For nearly half a century, first-order quantum phase
transitions (FOQPT) have been studiedintensely in various
contexts. False vacuum decay is a potential mechanism for
the Universe's evolutionpost-Big Bang, the Kibble-Zurek
mechanism can be generalized to FOQPTs, quantum
metastability hasimplications for reaction rate theory, and
the mechanisms behind FOQPTs can help answer
fundamentalquestions regarding non-equilibrium quantum
dynamics. Despite theoretical advancements,
directobservation and study of these dynamics have remained
elusive due to their non-perturbative nature.However, recent
breakthroughs in quantum technology have enabled
unprecedented experimentalinvestigation into this
fundamental phenomenon. Here, we utilize a quantum annealer
with 5564superconducting flux qubits subjected to transverse
and longitudinal fields arranged in a ring to
directlyobserve FOQPT dynamics, revealing quantized bubble
formation. Moreover, we identify a parameterregime on the
quantum annealer where we observe coherent scaling laws in
driven many-body dynamicsof 5564 qubits for over 1 μs,
which is more than 1000 qubit time units. This study opens
avenues forinvestigating previously inaccessible time
scales, system sizes, dimensionality, and topology
ofmany-body dynamics, marking a significant milestone in the
study of complex quantum systems andpaving the way for
future breakthroughs in quantum simulation.},
