Time-space complexity of quantum search algorithms in symmetric cryptanalysis: applying to AES and SHA-2 [PDF]

, 2018
Performance of cryptanalytic quantum search algorithms is mainly inferred from query complexity which hides overhead induced by an implementation. To shed light on quantitative complexity analysis removing hidden factors, we provide a framework for ...

Feynman checkers: towards algorithmic quantum theory

, 2020
We survey and develop the most elementary model of electron motion introduced by R.Feynman. It is a game, in which a checker moves on a checkerboard by simple rules, and we count the turns.

Quantum wave packet transforms with compact frequency support

Different kinds of wave packet transforms are widely used for extracting multi-scale structures in signal processing tasks. This paper introduces the quantum circuit implementation of a broad class of wave packets, including Gabor atoms and wavelets ...

An Alternative Formulation of the Quantum Phase Estimation Using Projection-Based Tensor Decompositions

In this paper an alternative version of the quantum phase estimation is proposed, in which the Hadamard gates at the beginning are substituted by a quantum Fourier transform.
