## Here comes the SU(N): multivariate quantum gates and gradients

This repository contains the code to reproduce all results and numerical figures/plots

of the paper

["Here comes the SU(N): multivariate quantum gates and gradients"](arxiv.org/abs/2303.11355)

by Roeland Wiersema, Dylan Lewis, David Wierichs, Juan Carrasquilla and Nathan Killoran.

The repository is structured as follows:

- `requirements.txt`: All required Python packages to run the programs. We used Python 3.10. The file can be used via `pip install -r requirements.txt`

- `run_single_qubit.py`: Execute this file to produce the data and plots for the toy example on a single qubit (Figs. 3, 4, E1)

- `run_vqe.py`: Execute this file to produce the data and plots for the 10-qubit VQE optimization example (Figs. 7, 8)

- `single_qubit.py`: Additional functions used in `run_single_qubit.py`

- `vqe.py`: Additional functions used in `run_vqe.py`

- `figures/`: All produced figures are stored here

- `data/`: All prodcued data is stored here

(Note that no code is provided (yet) to create Figs. 5 and 6.)

In general, the programs are written such that pre-computed data is loaded if possible, in order to allow quick changes to the figures

and to save computation efforts. If you want to reproduce the data from scratch (randomness seeds are fixed almost everywhere),

just move or delete the data locally and execute `run_vqe.py` or `run_single_qubit.py`.
