Quantum resource theories

E Chitambar, G Gour - Reviews of modern physics, 2019 - APS
Quantum resource theories (QRTs) offer a highly versatile and powerful framework for
studying different phenomena in quantum physics. From quantum entanglement to quantum …

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 …

[PDF][PDF] Mitigation of readout noise in near-term quantum devices by classical post-processing based on detector tomography

FB Maciejewski, Z Zimborás, M Oszmaniec - Quantum, 2020 - quantum-journal.org
We propose a simple scheme to reduce readout errors in experiments on quantum systems
with finite number of measurement outcomes. Our method relies on performing classical …

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 …

All sets of incompatible measurements give an advantage in quantum state discrimination

P Skrzypczyk, I Šupić, D Cavalcanti - Physical review letters, 2019 - APS
Some quantum measurements cannot be performed simultaneously; ie, they are
incompatible. Here we show that every set of incompatible measurements provides an …

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 …

Robustness of measurement, discrimination games, and accessible information

P Skrzypczyk, N Linden - Physical review letters, 2019 - APS
We introduce a resource theory of measurement informativeness. This allows us to define an
associated quantifier, which we call the robustness of measurement. It describes how much …

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 …

Complete resource theory of quantum incompatibility as quantum programmability

F Buscemi, E Chitambar, W Zhou - Physical review letters, 2020 - APS
Measurement incompatibility describes two or more quantum measurements whose
expected joint outcome on a given system cannot be defined. This purely nonclassical …

Application of the resource theory of channels to communication scenarios

R Takagi, K Wang, M Hayashi - Physical Review Letters, 2020 - APS
We introduce a resource theory of channels relevant to communication via quantum
channels, in which the set of constant channels—useless channels for communication tasks …
