We know you're busy, so we've rounded up the most important updates you need to know about this month. Let’s dive in!
In this issue
🔨 Massive new release: PennyLane v0.45
🏆 Earn prizes by claiming bounties or completing the PennyLane x unitaryHACK challenge
🎉 New milestone: 2000+ papers powered by PennyLane
🧩 Can you solve our quantum puzzle?
Algorithms assemble!
PennyLane v0.45 is officially live 🔨
Our latest release is packed with features designed to create meaningful quantum algorithms, from inspiration to implementation.
- Watch your algorithm get compiled step-by-step with our new workflow inspection tools
- Provide custom decomposition rules for each gate in your circuit
- Visualize your classical and quantum code together as a unified computational graph
- Get cooking with new gate sets, state preparations, and angle solvers
- And more!
Try out some of our newest features with the v0.45 coding challenge—and earn a newly minted v0.45 badge! Read our release blog for more details.

PennyLane cited in 2000+ papers 🎉
This year we passed an incredible milestone: the PennyLane white paper has now been cited more than 2000 times. From the beginning, you can see our open-source approach and community-based mindset at work (the paper has 68 co-authors!). It’s been incredible to see some of the amazing things people have done with PennyLane over the years, such as:
