Title: Separable states and their applications in computer science
Abstract: I'll discuss how optimizing over separable states (or equivalently, estimating whether a density matrix is separable or entangled) is comparable in difficulty to many important approximation problems in classical computer science, such as estimating the 2->4 norm of a matrix, or estimating the minimum expansion of small subsets of a graph. These connections yield new (classical) algorithms and lower bounds for these approximation problems, and may also yield new classes of interesting quantum states by adapting results from classical computer science.
