Quantum Cost Models for Cryptanalysis of Isogenies
(University of Waterloo, 2019-05-01)Isogeny-based cryptography uses keys large enough to resist a far-future attack from Tani’s algorithm, a quantum random walk on Johnson graphs. The key size is based on an analysis in the query model. Queries do not ... -
WKB Analysis of Tunnel Coupling in a Simple Model of a Double Quantum Dot
(University of Waterloo, 2008-12-16)A simplified model of a double quantum dot is presented and analyzed, with applications to spin-qubit quantum computation. The ability to trap single electrons in semiconductor nanostructures has led to the proposal of ...
