Quantum steering

R Uola, ACS Costa, HC Nguyen, O Gühne - Reviews of Modern Physics, 2020 - APS
Quantum correlations between two parties are essential for the argument of Einstein,
Podolsky, and Rosen in favor of the incompleteness of quantum mechanics. Schrödinger …

Semidefinite programming relaxations for quantum correlations

A Tavakoli, A Pozas-Kerstjens, P Brown… - Reviews of Modern Physics, 2024 - APS
Semidefinite programs are convex optimization problems involving a linear objective
function and a domain of positive-semidefinite matrices. Over the past two decades, they …

Colloquium: Incompatible measurements in quantum information science

O Gühne, E Haapasalo, T Kraft, JP Pellonpää… - Reviews of Modern …, 2023 - APS
Some measurements in quantum mechanics disturb each other. This has puzzled physicists
since the formulation of the theory, but only in recent decades has the incompatibility of …

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 …

General resource theories in quantum mechanics and beyond: operational characterization via discrimination tasks

R Takagi, B Regula - Physical Review X, 2019 - APS
We establish an operational characterization of general convex resource theories—
describing the resource content of not only states but also measurements and channels …

Quantifying quantum resources with conic programming

R Uola, T Kraft, J Shang, XD Yu, O Gühne - Physical review letters, 2019 - APS
Resource theories can be used to formalize the quantification and manipulation of resources
in quantum information processing such as entanglement, asymmetry and coherence of …

Thermodynamic approach to quantifying incompatible instruments

CY Hsieh, SL Chen - Physical Review Letters, 2024 - APS
We consider a thermodynamic framework to quantify instrument incompatibility via a
resource theory subject to thermodynamic constraints. We use the minimal thermalization …

Quantum incompatibility witnesses

C Carmeli, T Heinosaari, A Toigo - Physical review letters, 2019 - APS
We demonstrate that quantum incompatibility can always be detected by means of a state
discrimination task with partial intermediate information. This is done by showing that only …

Operational relevance of resource theories of quantum measurements

M Oszmaniec, T Biswas - Quantum, 2019 - quantum-journal.org
For any resource theory it is essential to identify tasks for which resource objects offer
advantage over free objects. We show that this identification can always be accomplished …

Incompatibility robustness of quantum measurements: a unified framework

S Designolle, M Farkas, J Kaniewski - New Journal of Physics, 2019 - iopscience.iop.org
In quantum mechanics performing a measurement is an invasive process which generally
disturbs the system. Due to this phenomenon, there exist incompatible quantum …
