What a day for quantum information… Yet I am very proud to announce my first single author paper and in some sense a culmination of my work the last two years. It’s on a genuine theory of multi-indexed Schatten spaces: scirate.com/arxiv/2610.0... 🔗📄 What does this mean and what is it useful for?

New preprint with @sayantansen.bsky.social and @marcotomamichel.bsky.social!! In Fast and Sure-ious QPT, we describe a simple and rigorous way to lift any QST algorithm (in fidelity) to a QPT algorithm, while allowing for all guarantees to transfer! scirate.com/arxiv/2609.3...

Did you know there was a quartic quantum advantage for SDP solving? Unfortunately, we show it's only a quadratic speedup by dequantizing the Quantum OR lemma... 🥲 But, our quantum-inspired algorithm is the first sublinear time classical solver for general sparse SDPs! 🥳 arxiv.org/abs/2609.40302

A very important message from Omer Reingold to our TCS community, especially us (arg, already) senior researchers: "snap out of it." Please, digest, and share. theorydish.blog/2026/09/29/s...
