New blog post out! ✨
I give here a visual introduction to algebraic topology in the context of quantum error correction. You will learn about manifolds, cellulations, chain complexes, and their relation to CSS codes like the surface code. Enjoy! :)

The goal was to expose them to some of the quantum nonsense that's out there (thank you @dulwichquantum.bsky.social), help them understand the incentives of all the parties involved, and teach them critical thinking skills. I hope this will be helpful in their future careers!

I've been running a Lean seminar at CWI/UvA for some time. We now started formalizing Appleby's result on the structure of the single-qudit Clifford group. Here's the blueprint and GitHub repository in case you're interested.
