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 …

Quantum fidelity measures for mixed states

YC Liang, YH Yeh, PEMF Mendonça… - Reports on Progress …, 2019 - iopscience.iop.org
Applications of quantum technology often require fidelities to quantify performance. These
provide a fundamental yardstick for the comparison of two quantum states. While this is …

Principles of quantum communication theory: A modern approach

S Khatri, MM Wilde - arXiv preprint arXiv:2011.04672, 2020 - arxiv.org
This is a preliminary version of a book in progress on the theory of quantum communication.
We adopt an information-theoretic perspective throughout and give a comprehensive …

Quantum conditional mutual information and approximate Markov chains

O Fawzi, R Renner - Communications in Mathematical Physics, 2015 - Springer
A state on a tripartite quantum system A ⊗ B ⊗ CA⊗ B⊗ C forms a Markov chain if it can be
reconstructed from its marginal on A ⊗ BA⊗ B by a quantum operation from B to B ⊗ CB⊗ C …

Asymptotic estimates in information theory with non-vanishing error probabilities

VYF Tan - Foundations and Trends® in Communications and …, 2014 - nowpublishers.com
This monograph presents a unified treatment of single-and multi-user problems in
Shannon's information theory where we depart from the requirement that the error …

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 …

Fundamental limits on correlated catalytic state transformations

R Rubboli, M Tomamichel - Physical Review Letters, 2022 - APS
Determining whether a given state can be transformed into a target state using free
operations is one of the fundamental questions in the study of resource theories. Free …

Quantum metrology in the finite-sample regime

JJ Meyer, S Khatri, DS França, J Eisert… - arXiv preprint arXiv …, 2023 - arxiv.org
In quantum metrology, one of the major applications of quantum technologies, the ultimate
precision of estimating an unknown parameter is often stated in terms of the Cram\'er-Rao …

α-z-Rényi relative entropies

KMR Audenaert, N Datta - Journal of Mathematical Physics, 2015 - pubs.aip.org
We consider a two-parameter family of Rényi relative entropies D α, z (ρ∥ σ) that are
quantum generalisations of the classical Rényi divergence D α (p∥ q). This family includes …

Resource theory of quantum uncomplexity

N Yunger Halpern, NBT Kothakonda, J Haferkamp… - Physical Review A, 2022 - APS
Quantum complexity is emerging as a key property of many-body systems, including black
holes, topological materials, and early quantum computers. A state's complexity quantifies …
