Benjamin Lovitz
I am an NSF postdoc and Zelevinsky fellow at Northeastern University, working with Harm Derksen. I earned my PhD from the University of Waterloo, where I was supervised by William Slofstra and John Watrous. Prior to that, I completed my MSc at the University of Waterloo under the supervision of Norbert Lütkenhaus. I obtained my B.A. from Bates College, with a double major in mathematics and physics (honors).
Often, the key to solving a problem lies in uncovering some underlying symmetry. In most of my work, I find and leverage algebraic-geometric and representation-theoretic symmetries in problems coming from tensor decompositions, quantum information theory, and optimization.
Keywords: CP decomposition, secant variety, identifiability, stabilizer rank, quantum property testing, quantum state discrimination, entanglement theory, entangled subspaces, quantum de Finetti theorem, polynomial optimization, semidefinite programming.
