Xanadu

aid: xanadu-ai
name: Xanadu
description: Xanadu is a Canadian photonic quantum computing company building room-temperature, fault-tolerant, scalable quantum
  computers based on photonic continuous-variable (CV) and Gaussian boson sampling architectures. Xanadu maintains a large
  open-source software stack — most notably PennyLane (the cross-platform framework for quantum differentiable programming,
  quantum chemistry, and quantum machine learning), Catalyst (a JIT/MLIR compiler for hybrid quantum-classical programs),
  the PennyLane Lightning family of high-performance state-vector and tensor-network simulators, the PennyLane Plugin ecosystem
  (Qiskit/IBM, AWS Braket, Cirq, Rigetti, IonQ, AQT, Quantinuum, Qulacs, ProjectQ, and Xanadu's own Strawberry Fields), MrMustard,
  Jet, FlamingPy, The Walrus, Blackbird (the CV quantum assembly language), XIR, and the Xanadu Quantum Codebook. Xanadu hardware
  milestones include the X8 photonic chip, Borealis (quantum advantage demonstration on a 216-mode programmable Gaussian boson
  sampler), and Aurora (the first modular, networked photonic quantum computer combining server racks and kilometres of optical
  fibre). The Xanadu Cloud — the original photonic-hardware-as-a-service offering with REST/Python/CLI access to Borealis
  and X8 — has been retired (the `xanadu-cloud-client` and Strawberry Fields repos are archived), and Xanadu's developer-facing
  surface today centres on the PennyLane Python ecosystem and hardware execution via PennyLane plugins against partner cloud
  platforms.

  description: 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.
