Quantum circuit models for many-body physics #
In the first part of the talk, I will provide a pedagogical overview of recent literature focusing on quantum circuits and quantum cellular automata (QCA) as useful theoretical models in many-body physics, both in and out of equilibrium. I will highlight in particular the features that allow them to mimic the behaviour of realistic many-body systems, and explain their relevance for implementations in the quantum devices available today. In the second part of the talk, I will focus on some of my recent work on the subject, including exact results pertaining to the dynamics of entanglement in certain random circuits, and an experimental proposal to implement QCA in globally driven Rydberg-atom systems.
