Scalable Probes of Measurement-Induced Criticality
Scalable Probes of Measurement-Induced Criticality
We uncover a local order parameter for measurement-induced phase transitions: the average entropy of a single reference qubit initially entangled with the system. Using this order parameter, we identify scalable probes of measurement-induced criticality that are immediately applicable to advanced quantum computing platforms. We test our proposal on a $1+1$ …
