Postselection-Free Reconstruction of Monitored SPT Flux-Charge Responses
Shuai Zeng
A class of monitored topological invariants compares ordinary and symmetry-twisted quantum trajectories with identical stochastic records, so direct estimation requires exponential…

Thermal Activation of Divergent Distillable Entanglement under Non-Abelian Strong Symmetry
Shuai Zeng
Heating usually destroys quantum entanglement. We show that thermalization constrained to a non-Abelian strong-symmetry sector can instead generate a distillable resource that dive…

Reliability Is Not Free in Universal Quantum Work Extraction
Shuai Zeng
Universal work extraction shows that input-state knowledge is unnecessary to attain the asymptotic free-energy rate. We ask whether this first-order universality extends to reliabi…
