| Abstract: |
Harnessing dissipation is a challenge of increasing significance for quantum science, with implications ranging from dissipative quantum state preparation and quantum computation, to non-equilibrium quantum phases of matter and quantum thermodynamics. In this talk, I will present recent advances toward developing a general control-theoretic framework for analysis and synthesis of open-system dynamics that admits a desired quantum state as its unique asymptotically stable state. In particular, I will present necessary and sufficient conditions for a target pure entangled state to be stabilizable by dissipative Markovian dynamics subject to physical locality constraints. If the conditions for purely dissipative stabilization are not met, I will further address whether the objective may be achieved conditional upon initialization in a proper subspace and/or by additionally exploiting Hamiltonian control. I will conclude by surveying open problems and ongoing work addressing extensions to quasi-local discrete-time dynamics and mixed-state stabilization.
