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…
