Structured dissipation steady states in open quantum dynamics on an ion trap processor.

Understanding novel behavior of driven-dissipative quantum systems is critical to research of many-body open systems in nature. The relative strengths of coherent drive and dissipation in these systems may lead to distinct phases in a non-equilibrium steady-state. Trapped ions are an excellent platform to model these systems, owing to long coherence times, widely tunable coherent interactions, and controllable dissipation from optical beams. Here we utilize trapped $^{171}$Yb$^+$ ions to probe at non-equilibrium steady-state physics. In particular, we explore beyond the standard randomized dissipation to examine steady-states where the dissipation mechanism has some inherent structure and corelation. We demonstrate site-selective individual reset as a highly flexible parameter for controlling the steady-state, branching this work to broader explorations of reservoir engineering.
