🚨 New paper on arXiv: Analytically Continuing the Randomized Measurement Toolbox w/ Akash Vijay, Ayush Raj, Benoît Vermersch, Andreas Elben, and Laimei Nie

We develop a framework for extracting non-polynomial analytic functions of density matrices in randomized measurement experiments by a method of analytical continuation, and demonstrate its application to estimating von Neumann entanglement entropy from experimental Rényi data.
