Variational Quantum Eigensolver (VQE) Tutorial

Download the requirements.txt

Setup

Requires Python 3.10–3.12 (cirq-core==1.4.0 needs numpy<2, which has no wheels for newer versions; tested with Python 3.12).

python3.12 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

Then open the notebooks in Jupyter, e.g. with pip install jupyterlab && jupyter lab.
