University of Oxford Team Develops Ribbon ZX Calculus for Two-Dimensional Yang Mills Theory

Quantum ZeitgeistJune 15, 20264 min read

Previously confined to qubit quantum processes, ZX calculus now describes two-dimensional Yang-Mills theory, bridging a gap between quantum information and gauge theory. This extension reveals a shared algebraic structure underpinning both frameworks, utilising Frobenius algebras and topological quantum field theory diagrammatics. Consequently, a new avenue opens for applying ZX calculus to the study of low-dimensional gravity.

Gabriel Wong of University of Oxford and colleagues have extended the graphical formalism of ZX calculus, typically used for quantum information and computing, to the realm of two-dimensional Yang Mills theory. Leveraging a shared Hopf Frobenius algebraic structure, the team generalised ZX calculus by identifying a common foundation underpinning both frameworks and describable through the diagrammatics of two-dimensional topological quantum field theory. This provides a key link between quantum computation and gauge theory, potentially enabling the application of ZX calculus to…
