Topological Quantum Computing, September 12 – 16, 2011

We are pleased to announce the upcoming workshop, Quantum: Topology, Information, Computation, to be held at Stony Brook University from September 12 through September 16, 2011. Quantum has become ubiquitous in topology, information, and computation. The central theme of the workshop evolves around mathematical and scientific challenges in the topological approach to building a large-scale quantum computer. Specific topics will include: Classification of topological insulators via K-theory 3D topological phases of matter and engineering of materials that support universal quantum computation Tensor networks and quantum algorithms Mathematical frameworks for topological phases of matter such as field theories, lattice models and higher categories

Co- organized by: Mike Freedman, Matthew Hastings, Alexander Kirillov and Zhenghan Wang. For more information about registration please email:
