Haar random and pretty good measurements for state estimation

Title: Haar random and pretty good measurements for state estimation

Speaker: Dr. Maria Quadeer, Nanyang Technological University

Abstract of Talk: In this talk, I will introduce quantum state tomography as an estimation theoretic  problem, and discuss some of my earlier work [1]. I will then expand upon my recent work [2] that builds on the same formalism and tries to address the issue of measurement choices for the state estimation problem.
