abstract = {False vacuum decay is a potential mechanism governing the
evolution of the early Universe, with profound connections
to non-equilibrium quantum physics, including quenched
dynamics, the Kibble-Zurek mechanism, and dynamical
metastability. The non-perturbative character of the false
vacuum decay and the scarcity of its experimental probes
make the effect notoriously difficult to study, with many
basic open questions, such as how the bubbles of true vacuum
form, move and interact with each other. Here we utilize a
quantum annealer with 5564 superconducting flux qubits to
directly observe quantized bubble formation in real time --
the hallmark of false vacuum decay dynamics. Moreover, we
develop an effective model that describes the initial bubble
creation and subsequent interaction effects. We demonstrate
that the effective model remains accurate in the presence of
dissipation, showing that our annealer can access coherent
scaling laws in driven many-body dynamics of 5564 qubits for
over 1μs, i.e., more than 1000 intrinsic qubit time units.
This work sets the stage for exploring late-time dynamics of
the false vacuum at computationally intractable system
sizes, dimensionality, and topology in quantum annealer
platforms.},
