Provable Quantum--Classical Separation for Continuous Gibbs Sampling

Enrico Olivucci, Mariia Sobchuk, Sehmimul Hoque +4

We prove the first quantum--classical separation for a sampling problem over a continuous domain. For a class of Gibbs states $p\propto e^{-\beta E}$ on the torus ${\mathbb{T}}^d$ with sm…
