Quantum algorithms promise speedups for sampling and optimization

By PulseAugur Editorial · [1 sources] ·

Researchers have developed new quantum algorithms that offer speedups for sampling from complex probability distributions and for non-convex optimization tasks. These algorithms enhance classical methods like Langevin Monte Carlo and Hamiltonian Monte Carlo by incorporating quantum subroutines for mean and gradient estimation. The work applies to distributions with specific properties, providing convergence guarantees in Wasserstein distance and Kullback--Leibler divergence, and also demonstrates how faster sampling can accelerate optimization for various objectives.

    Quantum Speedups for Sampling and Non-convex Optimization with Stochastic Oracles

    arXiv:2504.03626v2 Announce Type: replace-cross Abstract: We present quantum speedups for sampling from distributions of the form $\pi\propto e^{-f}$ on $\mathbb{R}^d$. We consider two stochastic oracle models: a stochastic gradient oracle, where $f=\frac{1}{n}\sum_{i=1}^n f_i $ …
