Strong-to-Weak Symmetry Breaking in Open Quantum Systems: From Discrete Particles to Continuum Hydrodynamics
Jacob Hauser, Kaixiang Su, Hyunsoo Ha +6
We explore the onset of spontaneous strong-to-weak symmetry breaking (SW-SSB) under U(1)-symmetric (i.e., charge-conserving) open-system dynamics. We define this phenomenon for qua…
Mixed-state learnability transitions in monitored noisy quantum dynamics
Hansveer Singh, Romain Vasseur, Andrew C. Potter +1
We consider learnability transitions in monitored quantum systems that undergo noisy evolution, subject to a global strong symmetry -- i.e., in addition to the measuring apparatus,…
Universal structure of measurement-induced information in many-body ground states
Zihan Cheng, Rui Wen, Sarang Gopalakrishnan +2
Unlike unitary dynamics, measurements of a subsystem can induce long-range entanglement via quantum teleportation. The amount of measurement-induced entanglement or mutual informat…
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…
