Categorical Semantics for Feynman Diagrams
Razin A. Shaikh, Stefano Gogioso
We introduce a novel compositional description of Feynman diagrams, with well-defined categorical semantics as morphisms in a dagger-compact category. Our chosen setting is suitabl…
CPM Categories for Galois Extensions
James Hefford, Stefano Gogioso
By considering a generalisation of the CPM construction, we develop an infinite hierarchy of probabilistic theories, exhibiting compositional decoherence structures which generalis…
Functorial evolution of quantum fields
Stefano Gogioso, Maria E. Stasinou, Bob Coecke
We present a compositional algebraic framework to describe the evolution of quantum fields in discretised spacetimes. We show how familiar notions from Relativity and quantum causa…
A Process-Theoretic Church of the Larger Hilbert Space
Stefano Gogioso
We show how to reconstruct a process theory of local systems starting from a global theory of reversible processes on a single global system, by using the purification principle. I…
Purification and time-reversal deny entanglement in LOCC-distinguishable orthonormal bases
Stefano Gogioso, Subhayan Roy Moulik
We give a simple proof, based on time-reversibility and purity, that a complete orthonormal family of pure states which can be perfectly distinguished by LOCC cannot contain any en…
Categorical Semantics for Time Travel
Nicola Pinzani, Stefano Gogioso, Bob Coecke
We introduce a general categorical framework to reason about quantum theory and other process theories living in spacetimes where Closed Timelike Curves (CTCs) are available, allow…
