Universal Low-rank Matrix Recovery from Pauli Measurements
Speaker(s): Yi-Kai Liu
Abstract: We study the problem of reconstructing an unknown matrix M, of rank r and dimension d, using O(rd poly log d) Pauli measurements. This has applications to compressed sensing methods for quantum state tomography.  We give a solution to this problem based on the restricted isometry property (... read more

Twisted Generalized Calabi-Yau Manifolds and Topological Sigma Models with Flux (Part 3)
Speaker(s): Yi Li
Abstract: In these lectures, we examine how twisted generalized Calabi-Yau (GCY) manifolds arise in the construction of a general class of topological sigma models with non-trivial three-form flux. The topological sigma model defined on a twisted GCY can be regarded as a simultaneous generalization of the mor... read more
