PennyLane is a Python quantum machine learning library by Xanadu Inc.
Train a quantum computer the same way as a neural network.
Machine learning on quantum hardware. Connect to quantum hardware using PyTorch, TensorFlow, JAX, Keras, or NumPy. Build rich and flexible hybrid quantum-classical models.
Device independent. Run the same quantum circuit on different quantum backends. Install plugins to access even more devices, including Strawberry Fields, Amazon Braket, IBM Q, Google Cirq, Rigetti Forest, Qulacs, Pasqal, Honeywell, and more.
Follow the gradient. Hardware-friendly automatic differentiation of quantum circuits.
Batteries included. Built-in tools for quantum machine learning, optimization, and quantum chemistry. Rapidly prototype using built-in quantum simulators with backpropagation support.
PennyLane requires Python version 3.7 and above. Installation of PennyLane, as well as all dependencies, can be done using pip:
python -m pip install pennylane
For an introduction to quantum machine learning, guides and resources are available on PennyLane's quantum machine learning hub:
- What is quantum machine learning?
- QML tutorials and demos
- Frequently asked questions
- Key concepts of QML
- QML videos
Tutorials and demonstrations
Take a deeper dive into quantum machine learning by exploring cutting-edge algorithms on our demonstrations page.
All demonstrations are fully executable, and can be downloaded as Jupyter notebooks and Python scripts.
If you would like to contribute your own demo, see our demo submission guide.
