Are you a computer scientist and don't know what an OTOC is, but want to understand the problem solved in the @Nature paper by @GoogleQuantumAI? We wrote a 2-page note that explains the motivation and presents a simplified version of the problem for arbitrary input size.

Today in @Nature, we published a breakthrough demonstration of verifiable quantum advantage using a measurement known as out-of-time-order correlator (OTOC), or Quantum Echoes. Performed on our Willow chip, it paves a path toward real-world applications → goo.gle/3Jqaqst

BREAKING NEWS The Royal Swedish Academy of Sciences has decided to award the 2025 #NobelPrize in Physics to John Clarke, Michel H. Devoret and John M. Martinis “for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit.”

The #QEC25 conference hosted by @Yale_QI was really excellent, and videos of all talks are available. So much recent progress on quantum error correction! qec25.yalepages.org


Congrats to authors! Nice and simple discussion of issues that needs attention with respect to quantum advantage. A similar and less concise question was discussed by Maria Schuld, some time back due to lack of reproducibility/advantage in context of QML.

The infectious enthusiasm of my wonderful co-authors (@RobertHuangHY, Soonwon Choi, @JarrodMcclean) drove this upbeat assessment of “The Vast World of Quantum Advantage." arxiv.org/abs/2508.05720

AI is used to quickly assemble ~2000 atoms without defects. As a fun demonstration of the technique, the authors created a #CatVideo about Schrödinger's cat—each pixel is an atom. PRL: go.aps.org/40Sx1ne PhysMag: go.aps.org/4fyNPps

are we finally getting rid of tokenization? "Dynamic Chunking for End-to-End Hierarchical Sequence Modeling" with a hierarchical “H-Net” that learns content-aware byte-level boundaries end-to-end, they eliminated fixed tokenization and surpasses BPE-based Transformers
