Welch Bounds and Quantum State Tomography
(University of Waterloo, 2008-12-22)In this thesis we investigate complete systems of MUBs and SIC-POVMs. These are highly symmetric sets of vectors in Hilbert space, interesting because of their applications in quantum tomography, quantum cryptography and ... -
Worst-Case to Average-Case Reductions for the SIS Problem: Tightness and Security
(University of Waterloo, 2019-07-30)We present a framework for evaluating the concrete security assurances of cryptographic constructions given by the worst-case SIVP_γ to average-case SIS_{n,m,q,β} reductions. As part of this analysis, we present the tightness ...
