Xanadu’s Quantum Framework PennyLane gets a new version

The latest release of PennyLane is now out and available for general release. The popular framework from Canadian Quantum Computing Company Xanadu is a framework that allows users to quickly get to grips with QML or Quantum Machine Learning. Version 0.20 comes with many new additions, including a new graphical circuit drawer, new quantum-aware optimizers, faster performance, smarter circuit decompositions, general hardware gradient support.

Here are some of the new features and changes.

  • Shiny new circuit drawer! 
  • New and improved quantum-aware optimizers
    • Perform gradient descent on the special unitary group
    • Improved quantum natural gradient support
  • Characterize your quantum models with classical QNode reconstruction 
  • Faster performance with optimized quantum workflows
  • Batch execute quantum circuits
    • 𝑛nth order derivatives on hardware
    • Smarter circuit decomposition strategies
    • Support for TensorFlow AutoGraph mode with quantum hardware
  • Hardware gradients of arbitrary operations 
  • Define device-specific custom decompositions

The Quantum Mechanic

The Quantum Mechanic is the journalist who covers quantum computing like a master mechanic diagnosing engine trouble - methodical, skeptical, and completely unimpressed by shiny marketing materials. They're the writer who asks the questions everyone else is afraid to ask: "But does it actually work?" and "What happens when it breaks?" While other tech journalists get distracted by funding announcements and breakthrough claims, the Quantum Mechanic is the one digging into the technical specs, talking to the engineers who actually build these things, and figuring out what's really happening under the hood of all these quantum computing companies. They write with the practical wisdom of someone who knows that impressive demos and real-world reliability are two very different things. The Quantum Mechanic approaches every quantum computing story with a mechanic's mindset: show me the diagnostics, explain the failure modes, and don't tell me it's revolutionary until I see it running consistently for more than a week. They're your guide to the nuts-and-bolts reality of quantum computing - because someone needs to ask whether the emperor's quantum computer is actually wearing any clothes.
