Quantum Cellular Automata workshop

This workshop is co-hosted by Jeongwan Haah, David Long and Dominic Williamson

Quantum cellular automata (QCA), or more properly locality-preserving unitaries, have emerged as a new frontier in the study of topological phases and symmetries in theoretical physics. In the context of the topological phases of matter, QCA appear as disentangling transformations of invertible states and localized phases and are destined to provide a new homotopy spectrum indexed by spatial dimensions. The subject calls for renewed attention to operator algebras in many-body physics and finds growing connections to recent generalized symmetries. This Q-FARM workshop aims to enhance appreciation of these facets and facilitate further developments.
