Learning Hard Quantum Distributions with Variational Autoencoders

Original Paper

You can find the original paper here.

Goal

The goal of this project was to analyze how the depth of the neural network (NN) affected the fidelity (measure of reconstruction accuracy) of resolving compressed quantum many-body states using Variational-Autoencoders (VAEs).

That is, we sample the probability density of the state, given by |Ψi (t)|2, and reconstruct this distribution using the generative model and determine fidelity.
