If you have a question about this talk, please contact Mike Gunn. Isolated quantum many-body systems, if initialised in states of low entanglement, typically evolve towards states of high (volume law) entanglement. I will first give a coarse-grained description for entanglement production obtained using simple minimal models (quantum circuits made up of randomly chosen gates). This description involves a minimal ‘membrane’ in spacetime. In the second part of the talk I will discuss what happens to entanglement generation when the entangling unitary evolution is interspersed with projective measurements, which tend to disentangle degrees of freedom. I will show that there is a phase transition as a function of the rate of measurements and that this phase transition is closely related to classical percolation.
