Observing quantum measurement collapse as a learnability phase transition
Utkarsh Agrawal, Javier Lopez-Piqueres, Romain Vasseur +2
The mechanism by which an effective macroscopic description of quantum measurement in terms of discrete, probabilistic collapse events emerges from the reversible microscopic dynam…
Critical phase and spin sharpening in SU(2)-symmetric monitored quantum circuits
Shayan Majidy, Utkarsh Agrawal, Sarang Gopalakrishnan +3
Monitored quantum circuits exhibit entanglement transitions at certain measurement rates. Such a transition separates phases characterized by how much information an observer can l…
Quantum Coding Transitions in the Presence of Boundary Dissipation
Izabella Lovas, Utkarsh Agrawal, Sagar Vijay
We investigate phase transitions in the encoding of quantum information in a quantum many-body system due to the competing effects of unitary scrambling and boundary dissipation. S…
