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?

This point regarding AI-produced proofs is of course not new, but is beautifully put here. www.quantamagazine.org/is-ai-the-en... @quantamagazine.org

The very last sentence, by Litt, is the only one truly irking me. "If we can’t adapt, he added, “whose fault is that?”" I wonder. Whose fault would it be, bringing an overfunded sledgehammer to the foundations of a centuries-old endeavor without giving a damn and requiring it adapt in merely years?

In a new preprint with Hao-Chung Cheng and @marcotomamichel.bsky.social, we give the exact strong converse exponent for the private capacity. The techniques used extend those recently put forward by my co-authors for the quantum capacity and include a new Renyi quantity. scirate.com/arxiv/2609.3...
