QuantumFlow: A Quantum Algorithms Development Toolkit

Installation for development

It is easiest to install QuantumFlow's requirements using conda.

git clone https://github.com/rigetti/quantumflow.git
cd quantumflow
conda install -c conda-forge --file requirements.txt
pip install -e .

You can also install with pip. However some of the requirements are tricky to install (notably tensorflow & cvxpy), and (probably) not everything in QuantumFlow will work correctly.

git clone https://github.com/rigetti/quantumflow.git
cd quantumflow
pip install -r requirements.txt
pip install -e .

Example

Train the QAOA algorithm, with back-propagation gradient descent, to perform MAXCUT on a randomly chosen 6 node graph.

./examples/qaoa_maxcut.py --verbose --steps 5 --nodes 6 random
