SUMMARY:Moghaddam: Detecting entanglement phase transitions in monitored qu
 antum circuits through fluctuations
CLASS:PUBLIC
DESCRIPTION:Speaker: Dr. Ali Ghorban Zadeh Moghaddam\nInstitute of Speaker:
  Tampere University\, Finland\nTopics:\n\n Location:\n  Name: IFW (D2E.27\
 , IFW Dresden)\n  Street: Helmholtzstraße 20\n  City: 01069 Dresden\n  Ph
 one: \n  Fax: \nDescription: Recently discovered measurement-induced entan
 glement phase transitions in monitored quantum circuits provide a novel ex
 ample of far-from-equilibrium quantum criticality. However\, a fundamental
  impediment to unraveling these phase transitions is characterizing entang
 lement through quantum-state tomography\, which requires an exponential nu
 mber of measurements relative to subsystem size in practice. In this talk\
 , I will introduce an efficient strategy that bypasses the need for direct
  measurements of entanglement entropy. Our proposed method offers a scalab
 le approach to capturing entanglement transitions in symmetric monitored q
 uantum circuits. Drawing parallels to entanglement entropy and mutual info
 rmation\, we also demonstrate the utility of both bipartite and multiparti
 te fluctuations in analyzing measurement-induced criticality. Remarkably\,
  I will argue that the phase transition can be revealed by measuring fluct
 uations of only a handful of qubits. .
