Entanglement Domain Walls in Monitored Quantum Circuits and the Directed Polymer in a Random Environment
Yaodong Li, Sagar Vijay, Matthew P. A. Fisher
Abstract
The properties of the volume-law-entangled phase of weakly monitored quantum circuits are related to the classical statistical mechanics of a directed polymer in a random environment, shedding light on the stability of volume-law entanglement in the presence of repeated projective measurements.
