Laura Lewis @laura-lewis.bsky.social · 05/10/2026Just posted a hefty update to the paper! We improve the classical post-processing time and add a lower bound showing optimality in each parameter up to log factors. 050
Laura Lewis @laura-lewis.bsky.social · 01/07/2026New paper with Ewin and John on learning local Lindbladians! arxiv.org/abs/2606.30358 As a special case, we also get structure learning of Hamiltonians from high-temperature Gibbs states, which was wide open before our work 🙂 1141

Here is the first post: ‘Round-robin CCZ is all you need’. sunnyzhiyanghe.github.io/blog/round-robin-ccz/ It shows a fun observation on CCZ gates, proved by Claude Opus 4.8 and verified in Lean by an auto-formalization model MerLean. The blog has the full story.sunnyzhiyanghe.github.ioAI-Derived: Round-robin CCZ is All You NeedAfter much procrastination, I am starting a blog with a fun AI-derived observation. Here is a note, the abstract says it all: Round-robin CCZ is All You Need. 1121
