Self-trapping of photons: a dissipation-induced classical to quantum transition — •Sebastian Schmidt1, James Raftery2, Darius Sadri2, Hakan Tureci2, and Andrew Houck2 — 1Institute of Theoretical Physics, ETH Zurich, Switzerland — 2Department of Electrical Engineering, Princeton University, USA
We discuss the theoretical proposal and recent experimental observation of a novel dissipation driven dynamical localization transition of strongly correlated photons in an extended superconducting circuit consisting of two coupled resonators, each containing a superconducting qubit. Interaction with an environment has been argued to provide a mechanism for the emergence of classical behavior from a quantum system. Surprisingly, homodyne measurements reveal the observed localization transition to be from a regime of classical oscillations into a macroscopically self-trapped state manifesting revivals, a fundamentally quantum phenomenon. This experiment also demonstrates a new class of scalable quantum simulators with well controlled coherent and dissipative dynamics suited to the study of quantum many-body phenomena out of equilibrium.
