Quantum Cost Models for Cryptanalysis of Isogenies
Jaques, Samuel (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 ... -
Spectral properties of tensor products of channels
Jaques, Samuel; Rahaman, Mizanur (Elsevier, 2018-09-15)We investigate spectral properties of the tensor products of two completely positive and trace preserving linear maps (also known as quantum channels) acting on matrix algebras. This leads to an important question of when ...
