Quantum optical systems of cold atoms, ions and molecules provide one of the best ways to implement quantum simulation of many body systems. In this talk we will discuss some recent theoretical and experimental developments towards "open system" quantum simulation, where a many body system is coupled to an engineered environment. This provides a new scenarios to prepare entangled states in quantum information, and leads to a new non-equilibrium condensed matter physics of driven-dissipative systems. Specific examples to be discussed include an open system Rydberg quantum simulator, and a related experiment with trapped ions demonstrating preparation of GHZ states and dynamical quantum phase transitions. In addition, we briefly touch topics like Majorana fermions induced by dissipation, and dissipative d-wave pairing.


Colloquia are held Tuesdays in Room 1410 at 4:00 pm (preceded by light refreshments at 3:30). If you have additional questions, please call 301-405-5946.
