PennyLane is one of 14 APIs that [Xanadu](https://apis.io/providers/xanadu-ai/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Quantum Machine Learning, Differentiable Programming, Hybrid, and Python. The published artifact set on APIs.io includes API documentation, an API reference, a GitHub repository, and code examples.

PennyLane is the flagship open-source Python framework for quantum differentiable programming — train and optimize variational quantum circuits with the same automatic differentiation engines used in classical machine learning. PennyLane unifies quantum machine learning, quantum chemistry, and hybrid quantum-classical workflows behind a single device-abstraction API, interoperates with NumPy, PyTorch, JAX, and TensorFlow/Keras, and runs against 40+ simulators and hardware backends through its plugin ecosystem. Apache 2.0 licensed. 3,200+ GitHub stars.
