     "We learned in the [high-level](high-level.ipynb) notebook how to setup the quantum side of the calculation, which involves specifying a Hamiltonian, defining a trial wavefunction ansatz before performing shadow tomography to extract the AFQMC trial wavefunction. In this example, we will repeat these steps again for the case of H4 which was studied in the [paper](https://arxiv.org/pdf/2106.16235.pdf). Then we will outline how to interface the output of the quantum half of the calculation with [ipie](https://github.com/JoonhoLee-Group/ipie/) to perform AFQMC with the quantum trial wavefunction."
