General probabilistic theories: An introduction

M Plávala - Physics Reports, 2023 - Elsevier
We introduce the framework of general probabilistic theories (GPTs for short). GPTs are a
class of operational theories that generalize both finite-dimensional classical and quantum …

Quantifying continuity of characteristics of composite quantum systems

ME Shirokov - Physica Scripta, 2023 - iopscience.iop.org
We describe the most general form of the Alicki–Fannes–Winter method for obtaining
uniform continuity bounds for characteristics of composite quantum systems and consider …

No second law of entanglement manipulation after all

L Lami, B Regula - Nature Physics, 2023 - nature.com
Many fruitful analogies have emerged between the theories of quantum entanglement and
thermodynamics, motivating the pursuit of an axiomatic description of entanglement akin to …

Operational quantification of continuous-variable quantum resources

B Regula, L Lami, G Ferrari, R Takagi - Physical Review Letters, 2021 - APS
The diverse range of resources which underlie the utility of quantum states in practical tasks

Generalized Quantum Stein's Lemma and Second Law of Quantum Resource Theories

M Hayashi, H Yamasaki - arxiv preprint arxiv:2408.02722, 2024 - arxiv.org
The second law of thermodynamics is the cornerstone of physics, characterizing the
convertibility between thermodynamic states through a single function, entropy. Given the …

Asymptotic state transformations of continuous variable resources

G Ferrari, L Lami, T Theurer, MB Plenio - … in Mathematical Physics, 2023 - Springer
We study asymptotic state transformations in continuous variable quantum resource
theories. In particular, we prove that monotones displaying lower semicontinuity and strong …

Entanglement cost for infinite-dimensional physical systems

H Yamasaki, K Kuroiwa, P Hayden, L Lami - arxiv preprint arxiv …, 2024 - arxiv.org
We prove that the entanglement cost equals the regularized entanglement of formation for
any infinite-dimensional quantum state $\rho_ {AB} $ with finite quantum entropy on at least …
