Picturing general quantum subsystems
Octave Mestoudjian, Matt Wilson, Augustin Vanrietvelde +1
We extend the usual process-theoretic view on locality and causality in subsystems (based on the tensor product case) to general quantum systems (i.e.\ possibly non-factor, finite-…

A BV-Category of Spacetime Interventions
James Hefford, Matt Wilson
We use the Chu construction to functorially build BV-categories from duoidal categories, demonstrating that candidate models of BV-logic can be cofreely constructed from a fragment…

Generalised Process Theories
John H. Selby, Maria E. Stasinou, Matt Wilson +1
Process theories provide a powerful framework for describing compositional structures across diverse fields, from quantum mechanics to computational linguistics. Traditionally, the…
