Probing chiral topological states with permutation defects
Yarden Sheffer, Ruihua Fan, Ady Stern +2
The hallmark of two-dimensional chiral topological phases is the existence of anomalous gapless modes at the spatial boundary. Yet, the manifestation of this edge anomaly within th…

Exponentially Accelerated Sampling of Pauli Strings for Nonstabilizerness
Zhenyu Xiao, Shinsei Ryu
Quantum magic, quantified by nonstabilizerness, measures departures from stabilizer structure and underlies potential quantum speedups. We introduce an efficient classical framewor…
