Article 0 Reads 0 Citations Operational locality in global theories. Published: 13 July 2018
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, doi: 10.1098/rsta.2017.0321
Within a global physical theory, a notion of locality allows us to find and justify information-processing primitives, like non-signalling between distant agents. Here, we propose exploring the opposite direction: to take agents as the basic building blocks through which we test a physical theory, and recover operational notions of locality from signalling conditions. First, we introduce an operational model for the effective state spaces of individual agents, as well as the range of their actions. We then formulate natural secrecy conditions between agents and identify the aspects of locality relevant for signalling. We discuss the possibility of taking commutation of transformations as a primitive of physical theories, as well as applications to quantum theory and generalized probability frameworks. This 'it from bit' approach establishes an operational connection between local actions and local observations, and gives a global interpretation to concepts like discarding a subsystem or composing local functions.This article is part of a discussion meeting issue 'Foundations of quantum mechanics and their impact on contemporary society'.
Article 0 Reads 127 Citations The role of quantum information in thermodynamics—a topical review Published: 23 February 2016
Journal of Physics A: Mathematical and Theoretical, doi: 10.1088/1751-8113/49/14/143001
This topical review article gives an overview of the interplay between quantum information theory and thermodynamics of quantum systems. We focus on several trending topics including the foundations of statistical mechanics, resource theories, entanglement in thermodynamic settings, fluctuation theorems and thermal machines. This is not a comprehensive review of the diverse field of quantum thermodynamics; rather, it is a convenient entry point for the thermo-curious information theorist. Furthermore this review should facilitate the unification and understanding of different interdisciplinary approaches emerging in research groups around the world.
