Special Topology Seminar: The algebra and topology of “quantum cellular automata” (qca)

qca are locality preserving automorphisms of the endomorphism algebra of degrees of freedom (say qubits) scattered over a manifold. The locality hypothesis allows manifold topology, immersion theory, Kiby’s torus trick, and homotopy theory to interact with the usual discussions of $C^*$ algebras. I’ll explain a few results and open problems.
