Notebooks outlining how to reproduce the results of Unbiasing fermionic quantum Monte Carlo with a quantum computer.
Quantum Monte Carlo methods are a class of classical algorithms that can offer
an efficient solution to the many-electron schroedinger equation but are plagued
by the `fermion sign problem`

. Typically, a constraint is introduced to overcome
this problem at the cost of introducing an uncontrolled bias in the results. In
this paper, it was shown that a quantum computer could be used to prepare
complicated trial wavefunctions in order to unbias the classical results.

## Code Overview

The Code Overview notebook introduces the basic structure of the code provided in recirq to generate the trial wavefunction's prepare in the QCQMC paper.

## End-to-End

The End-to-End notebook provides and end-to-end example for the H4 molecule and interfaces with ipie to produce numbers similar to those reported in the QCQMC paper.

## Experimental Wavefunctions

The Experimental Wavefunctions notebook demonstrates how to download and analyze the experimental wavefunctions, which can reproduce the results in QCQMC.
