Optimal sampling of tensor networks targeting wave function's fast decaying tails

Optimal sampling of tensor networks targeting wave function's fast decaying tails

We introduce an optimal strategy to sample quantum outcomes of local measurement strings for isometric tensor network states. Our method generates samples based on an exact cumulative bounding function, without prior knowledge, in the minimal amount of tensor network contractions. The algorithm avoi...
