Catalysis in quantum information theory

P Lipka-Bartosik, H Wilming, NHY Ng - Reviews of Modern Physics, 2024 - APS
Catalysts open up new reaction pathways that can speed up chemical reactions while not
consuming the catalyst. A similar phenomenon has been discovered in quantum information …

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 …

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 …

Operational advantage of quantum resources in subchannel discrimination

R Takagi, B Regula, K Bu, ZW Liu, G Adesso - Physical review letters, 2019 - APS
One of the central problems in the study of quantum resource theories is to provide a given
resource with an operational meaning, characterizing physical tasks in which the resource …

Catalysis of entanglement and other quantum resources

C Datta, TV Kondra, M Miller… - Reports on Progress in …, 2023 - iopscience.iop.org
In chemistry, a catalyst is a substance which enables a chemical reaction or increases its
rate, while remaining unchanged in the process. Instead of chemical reactions, quantum …

How to quantify a dynamical quantum resource

G Gour, A Winter - Physical review letters, 2019 - APS
We show that the generalization of the relative entropy of a resource from states to channels
is not unique, and there are at least six such generalizations. Then, we show that two of …

Catalytic quantum teleportation

P Lipka-Bartosik, P Skrzypczyk - Physical Review Letters, 2021 - APS
In this work, we address fundamental limitations of quantum teleportation—the process of
transferring quantum information using classical communication and preshared …

One-shot operational quantum resource theory

ZW Liu, K Bu, R Takagi - Physical review letters, 2019 - APS
A fundamental approach for the characterization and quantification of all kinds of resources
is to study the conversion between different resource objects under certain constraints. Here …

Virtual quantum resource distillation: General framework and applications

R Takagi, X Yuan, B Regula, M Gu - Physical Review A, 2024 - APS
We develop the general framework of virtual resource distillation, an alternative distillation
strategy proposed in Phys. Rev. Lett. 132, 050203 (2024) 10.1103/PhysRevLett …

Fundamental limitations on distillation of quantum channel resources

B Regula, R Takagi - Nature Communications, 2021 - nature.com
Quantum channels underlie the dynamics of quantum systems, but in many practical settings
it is the channels themselves that require processing. We establish universal limitations on …
