Just 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.

New 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 🙂

I’m starting a blog! 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.

AI-Derived: Round-robin CCZ is All You Need
After 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.

Her Maths Story @hermathsstory.bsky.social · 21/05/2025
“(…) I started to notice gender imbalance in math (…). I hope that by continuing to pursue a research career, I can inspire other young women to (…) dive into mathematics with confidence.” – Laura Lewis ➡️ hermathsstory.eu/laura-lewis #WomenInMaths #WomenInQuantum @laura-lewis.bsky.social
The picture shows the Her Maths Story logo on top, below is a portrait foto of Laura Lewis. She’s wearing a black shirt, white jacket and glasses. She has long dark hair wearing it to one side. In the background you can see green hills and trees. Below the picture it says her name and Quantum information student.

With Dar Gilboa and Jarrod McClean, we prove a new quantum advantage for learning periodic neurons in the quantum statistical query model! arxiv.org/pdf/2503.20879 The hardness of this problem was studied long before this work by classical learning theorists. 🔎
