Measurement induced criticality in monitored quantum systems

Event Information:
Abstract: A novel aspect of recent experiments with quantum devices is that measurements can play an active role in preparing the state of the system, not just in diagnosing it. Unlike unitary evolution, the quantum collapse induced by local measurements can have a highly non-local impact on entangled quantum states, instantaneously destroying or creating new long distance correlations. I will review the surprising collective effects that can arise, such as measurement induced phase transitions and new entanglement structures.
