Entanglement entropy scaling laws from fluctuations of non-conserved quantities
Szczepan Głodzik, Kim Pöyhönen, Ali G. Moghaddam +1
Entanglement patterns reveal essential information on many-body states and provide a way to classify quantum phases of matter. However, experimental studies of many-body entangleme…
Postselection-free approach to monitored quantum dynamics and entanglement phase transitions
Kim Pöyhönen, Ali G. Moghaddam, Moein N. Ivaki +1
Measurement-induced entanglement phase transitions in monitored quantum circuits have stimulated activity in a diverse research community. However, the study of measurement-induced…
Exponential shortcut to measurement-induced entanglement phase transitions
Ali G. Moghaddam, Kim Pöyhönen, Teemu Ojanen
Recently discovered measurement-induced entanglement phase transitions in monitored quantum circuits provide a novel example of far-from-equilibrium quantum criticality. Here, we p…
Boiling Quantum Vacuum: Thermal Subsystems from Ground-State Entanglement
Ali G. Moghaddam, Kim Pöyhönen, Teemu Ojanen
In certain special circumstances, such as in the vicinity of a black hole or in a uniformly accelerating frame, vacuum fluctuations appear to give rise to a finite-temperature envi…
Many-body entanglement and topology from uncertainties and measurement-induced modes
Kim Pöyhönen, Ali G. Moghaddam, Teemu Ojanen
We present universal characteristics of quantum entanglement and topology through virtual entanglement modes that fluctuate into existence in subsystem measurements. For generic in…
