Abstract

The paper introduces a novel map to cast quantum systems into neural network form, enabling arbitrary paths in Feynman's path integral. It applies to interacting quantum systems away from Gaussian limits. The method uses the universal approximation theorem for neural networks to generate paths. The neural network outputs serve as paths for the path integral, representing a wide class of quantum systems statistically. This approach does not rely on Gaussian processes or stochastic time evolution but directly reinterprets path integrals in quantum mechanics and QFTs.
