Here are slides for my @qip2025.bsky.social tutorial on quantum error correction. doi.org/10.5281/zeno...

This is a mega-thread of all Microsoft problems related to topological qubits. NOTE: I skip the numerous news reports and press releases, this thread is for serious _scientific_ and procedural materials First retraction: Quantized Majorana Conductance, from Nature www.nature.com/articles/nat...
nature.com
RETRACTED ARTICLE: Quantized Majorana conductance - Nature
In a step towards topological quantum computation, a quantized Majorana conductance has been demonstrated for a semiconducting nanowire coupled to a superconductor.

The sensor for the light in my office seems to have a blind spot directly where my desk is. In the spirit of turning bugs into features I guess this forces me to get up and walk to the light switch every 10 minutes...

I'm trying to learn some basic category theory for quantum information, so I started reading "Categories for Quantum Theory" by Heunen and Vicary. It helps me to better grasp what category theory is really about since examples they give are all in my research area. books.google.com/books?id=FdG...

Categories for Quantum Theory
Monoidal category theory serves as a powerful framework for describing logical aspects of quantum theory, giving an abstract language for parallel and sequential composition, and a conceptual way to u...

We've been getting a lot of questions about alternate QEC codes, and are we looking into any? Yes! Here's experiments for two on Willow. The color code: arxiv.org/abs/2412.14256 Dynamic surface codes: arxiv.org/abs/2412.14360

Scaling and logic in the color code on a superconducting quantum processor
Quantum error correction is essential for bridging the gap between the error rates of physical devices and the extremely low logical error rates required for quantum algorithms. Recent error-correctio...

Found slides by Ankur Moitra (presented at a TCS For All event) on "How to do theoretical research." Full of great advice! My favourite: "Find the easiest problem you can't solve. The more embarrassing, the better!" Slides: drive.google.com/file/d/15VaT... TCS For all: sigact.org/tcsforall/

Google's new Project Mariner reminds me of my old SikuliX (sikulix.com) workflows, and just how finicky and slow automation on the user-input level can be. It may be useful while AI agents can't interface directly with other programs' internals, but surely not as a long-term solution?

With overleaf's brief hiatus today, just a reminder about the beauty that is latexmk (mg.readthedocs.io/latexmk.html) - automatically re-runs LaTeX the required number of times to correctly generate citations and cross-references. And it already comes bundled with most LaTeX distributions!

What happens when you take a quantum Floquet code and add spatial and temporal randomness to its evolution? Quite a bit! Our paper from a couple months ago explores this behaviour, using a disordered dynamic automorphism color code as a key example: scirate.com/arxiv/2410.0...
