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,…
Boundary Criticality in the 2d Random Quantum Ising Model
Gaurav Tenkila, Romain Vasseur, Andrew C. Potter
The edge of a quantum critical system can exhibit multiple distinct types of boundary criticality. We use a numerical real-space renormalization group (RSRG) to study the boundary…
Cheshire qudits from fractional quantum spin Hall states in twisted MoTe
Rui Wen, Andrew C. Potter
Twisted MoTe homobilayers exhibit transport signatures consistent with a fractional quantum spin Hall (FQSH) state. We describe a route to construct topological quantum memory…
Topological holography for fermions
Rui Wen, Weicheng Ye, Andrew C. Potter
Topological holography is a conjectured correspondence between the symmetry charges and defects of a -dimensional system with the anyons in a -dimensional topological ord…
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…
Classification of 1+1D gapless symmetry protected phases via topological holography
Rui Wen, Andrew C. Potter
Symmetry topological field theory (SymTFT) gives a holographic correspondence between systems with a global symmetry and a higher-dimensional topological field theory. In this fram…
