Picture-perfect Quantum Key Distribution
Aleks Kissinger, Sean Tull, Bas Westerbaan
We provide a new way to bound the security of quantum key distribution using only two high-level, diagrammatic features of quantum processes: the compositional behavior of compleme…

Space in Monoidal Categories
Pau Enrique Moliner, Chris Heunen, Sean Tull
The category of Hilbert modules may be interpreted as a naive quantum field theory over a base space. Open subsets of the base space are recovered as idempotent subunits, which for…

Two Roads to Classicality
Bob Coecke, John Selby, Sean Tull
Mixing and decoherence are both manifestations of classicality within quantum theory, each of which admit a very general category-theoretic construction. We show under which condit…
