AB  - 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.
