Ordered linear spaces and categories as frameworks for information-processing characterizations of quantum and classical theory
Howard Barnum, Alexander Wilce
We review some of our recent results (with collaborators) on information processing in an ordered linear spaces framework for probabilistic theories. These include demonstrations t…
Information processing in convex operational theories
Howard Barnum, Alexander Wilce
In order to understand the source and extent of the greater-than-classical information processing power of quantum systems, one wants to characterize both classical and quantum mec…
Quantum Simulations of Classical Annealing Processes
R. D. Somma, S. Boixo, H. Barnum +1
We describe a quantum algorithm that solves combinatorial optimization problems by quantum simulation of a classical simulated annealing process. Our algorithm exploits quantum wal…
Entanglement and Subsystems, Entanglement beyond Subsystems, and All That
Lorenza Viola, Howard Barnum
Entanglement plays a pervasive role nowadays throughout quantum information science, and at the same time provides a bridging notion between quantum information science and fields…
Coordinating quantum agents' perspectives: convex operational theories, quantum information, and quantum foundations
Howard Barnum
In this paper, I propose a project of enlisting quantum information science as a source of task-oriented axioms for use in the investigation of operational theories in a general fr…
