Probing for the Trace Estimation of a Permuted Matrix Inverse Corresponding to a Lattice Displacement

Heather Switzer, Andreas Stathopoulos, Eloy Romero +2

In this work, we study probing for the more general problem of computing the trace of a permutation of $A^{-1}$, say $P{A}^{-1}$. The motivation comes from Lattice QCD where we need…
