Tunable fractional Fourier transform implementation of electronic wave functions in atomically thin materials

open access: yesBeilstein Journal of Nanotechnology, 2018
A tunable fractional Fourier transform of the quantum wave function of electrons satisfying either the Schrödinger or the Dirac equation can be implemented in an atomically thin material by a parabolic potential distribution applied on a direction ...

Quantum hashing and Fourier transform

open access: yesJournal of Physics: Conference Series, 2020
In the paper based on the notion of small-biased sets we define the quantum transformation that describes the quantum hash function over the cyclic group. We discuss its similarity to the well-known Quantum Fourier Transform and show possible applications to constructing space-efficient algorithms in various computational scenarios, including two-party

Quantum Fourier transform for quantum sensing

open access: yes, 2020
The Quantum Fourier Transformation ($QFT$) is a key building block for a whole wealth of quantum algorithms. Despite its proven efficiency, only a few proof-of-principle demonstrations have been reported. Here we utilize $QFT$ to enhance the performance of a quantum sensor.
