Abstract
Author(s): Akash Vijay, Ayush Raj, Jonah Kudler-Flam, Benoît Vermersch, Andreas Elben, and Laimei Nie<br/><p>We develop a framework for extracting nonpolynomial analytic functions of density matrices in randomized measurement experiments by a method of analytical continuation. A central advantage of this approach, dubbed <i>stabilized analytic continuation</i> (SAC), is its robustness to statistical noise arising…</p><br/>[Phys. Rev.
