 Topological order and long-range entanglement   in strongly interacting cold-atom systems

摘 要：Topological order in 2D defines a brand-new type of quantum phases. Non-abelian topologically ordered many-body systems are believed to be the best candidate for fault-tolerant quantum computation. Topological order has been shown closely related to the ground-state entanglement of many-body systems, and has thus refreshed our understanding of quantum phases and phase transitions. In this presentation, I will introduce the motivation and the basic ideas for realizing topological order in many-body-system models for strongly interacting cold-atoms systems and discuss the entanglement nature of certain such realized topological order.
