      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
