Many-Body Dynamics Through Measurement and Feedback — •Jonas Lammers1,2 and Klemens Hammerer1,2 — 1Institut für Theoretische Physik, Leibniz Universität Hannover — 2Max-Planck-Institut für Gravtitationsphysik (Albert-Einstein-Institut), Hannover
Time-continuous homodyne measurements and feedback allow for efficient quantum control of a broad range of systems, such as cavity and circuit QED, atomic ensembles, or optomechanics. Here we consider interferometric measurements on an array of such systems. We derive the corresponding feedback master equation, and apply it for the generation of many-particle entangled, stationary states (such as Bell, GHZ, and W states), and for the engineering of non-equilibrium dynamics of many-body systems (such as dissipative Ising models).
