Coherence as a Resource for Shor's Algorithm

F Ahnefeld, T Theurer, D Egloff, JM Matera… - Physical Review Letters, 2022 - APS
Shor's factoring algorithm provides a superpolynomial speedup over all known classical
factoring algorithms. Here, we address the question of which quantum properties fuel this …

[HTML][HTML] Coherence and contextuality in a Mach-Zehnder interferometer

R Wagner, A Camillini, EF Galvão - Quantum, 2024 - quantum-journal.org
We analyse nonclassical resources in interference phenomena using generalized
noncontextuality inequalities and basis-independent coherence witnesses. We use recently …

Quantifying interference via coherence

Y Sun, S Luo - Annalen der Physik, 2021 - Wiley Online Library
Interference, which has its origin in the superposition principle, is one of the hallmarks of
wave mechanics and constitutes a versatile resource for many information processing tasks …

Different types of coherence: Young-type interference versus Dicke superradiance

D Bhatti, M Bojer, J von Zanthier - Physical Review A, 2021 - APS
Dicke superradiance, ie, the enhanced spontaneous emission of coherent radiation, is often
attributed to radiation emitted by synchronized dipoles coherently oscillating in phase. At the …

On the Role of Coherence in Shor's Algorithm

F Ahnefeld, T Theurer, D Egloff, JM Matera… - arXiv preprint arXiv …, 2022 - arxiv.org
Shor's factoring algorithm provides a super-polynomial speed-up over all known classical
factoring algorithms. Here, we address the question of which quantum properties fuel this …

Classical Invasive Description of Informationally‐Complete Quantum Processes

MF Richter, A Smirne, WT Strunz, D Egloff - Annalen der Physik, 2023 - Wiley Online Library
In classical stochastic theory, the joint probability distributions of a stochastic process obey
by definition the Kolmogorov consistency conditions. Interpreting such a process as a …

Quantum asymmetry and noisy multimode interferometry

F Albarelli, M Mazelanik, M Lipka, A Streltsov… - Physical Review Letters, 2022 - APS
Quantum asymmetry is a physical resource that coincides with the amount of coherence
between the eigenspaces of a generator responsible for phase encoding in interferometric …

Quantum versus classical transport of energy in coupled two-level systems

I Medina, SV Moreira, FL Semião - Physical Review A, 2021 - APS
We consider the problem of energy transport in a chain of coupled quantum systems with the
goal of shedding light on how nonclassical resources can affect transport. We study the …

Coherence revival and metrological advantage for moving Unruh-DeWitt detector

J Feng, J Wang, S Li - arXiv preprint arXiv:2111.01358, 2021 - arxiv.org
In this paper, we investigate the quantum coherence extraction for two accelerating Unruh-
DeWitt detectors coupling to a scalar background in $3+ 1$ Minkowski spacetime. We find …

Quantifying dynamical total coherence in a resource non-increasing framework

S Yang, C Yu - Quantum Information Processing, 2022 - Springer
We quantify the dynamical quantum resource in the resource non-increasing (RNI)
framework, namely the free dynamical resource is defined by the channels that cannot …
