Speaker: Sarang Gopalakrishnan
Host: Zlatko Minev, PhD.

Abstract:

Continuously monitored quantum systems can undergo "entanglement
transitions" in their steady states (conditioned on the measurement
outcomes). I will briefly review our understanding of entanglement
transitions and why it is challenging to observe them in realistic
experiments. I will introduce a variant on the entanglement
transition, called the "charge sharpening" transition, and explain
how it can be related to a transition in the ability of an
eavesdropper to "learn" the state of a system using local measurements.
