[HTML][HTML] Quantum advantages for transportation tasks-projectiles, rockets and quantum backflow
Consider a scenario where a quantum particle is initially prepared in some bounded region
of space and left to propagate freely. After some time, we verify if the particle has reached …

Design of quantum backflow in the complex plane
I Chremmos - Journal of Physics A: Mathematical and Theoretical, 2024 - iopscience.iop.org
A way is presented to design quantum wave functions that exhibit backflow, namely negative
probability current despite having a strictly positive spectrum of momentum. These wave …

Simulating quantum backflow on a quantum computer
A Goussev, J Joo - Physica Scripta, 2024 - iopscience.iop.org
Quantum backflow is a counterintuitive effect in which the probability density of a free
particle moves in the direction opposite to the particle's momentum. If the particle is …

Time-of-arrival distributions for continuous quantum systems
Using standard results from statistics, we show that for any continuous quantum system
(Gaussian or otherwise) and any observable $ A $(position or otherwise), the distribution …

Quantum backflow of a Dirac fermion on a ring
VD Paccoia, O Panella, P Roy - arXiv preprint arXiv:2201.12916, 2022 - arxiv.org
We study the quantum backflow problem of a relativistic charged Dirac fermion constrained
to move on a ring of radius $ R $. Using the relativistic current operator we compute the …
