A fundamental problem in statistics and learning theory is to test properties of distributions. We show that quantum computers can solve such problems with significant speed-ups. In particular, we give fast quantum algorithms for testing closeness between unknown distributions, testing independence between two distributions, and estimating the Shannon / von Neumann entropy of distributions. The distributions can be either classical or quantum, however our quantum algorithms require coherent…

Do one or more unknown quantum states exhibit a particular property or are they ǫ-far from having that property in l1 distance? This is an important question in quantum computing, formulated as a

The problem of obtaining estimates to within a multiplicative factor γ > 1 of the Shannon entropy of probability distributions and the von Neumann entropy of mixed quantum states is studied, and it is proved that no polynomial query algorithm can multiply the entropy of distributions with arbitrarily low entropy.

This work constructs a constant quantum-depth circuit for the task of multivariate trace estimation, inspired by the method of Shor error correction, and instantiates the latter application with a theorem on estimating nonlinear functions of quantum states with “well-behaved” polynomial approximations.
