Measurement and Entanglement Phase Transitions in All-To-All Quantum Circuits, on Quantum Trees, and in Landau-Ginsburg Theory
Adam Nahum, Sthitadhi Roy, Brian Skinner, Jonathan Ruhman
Abstract
A journey through several theoretical approaches to measurement-induced phase transitions is presented: exact results are shown to be possible in some cases, and new lines of inquiry are opened up, with outstanding questions clearly delineated.
