Our paper on Solvable Quantum Circuits in Tree+1 Dimensions is now published in @prxquantum.bsky.social ! Very happy with how this work turned out, possibly even happier that the title made it through peer review.

Aha, thanks for letting me know!

In this way we can fully characterize free cumulants and make exact predictions for (higher-order) OTOCs and correlations in matrix elements -- fundamental quantities in ETH.

New paper on arXiv = good excuse for a first post on Bluesky! In arxiv.org/abs/2509.08060 we present a simple quantum circuit model in which we can characterize quantum scrambling and explicitly establish recent extensions of the eigenstate thermalization hypothesis. A short thread 🧵
