I think this quote is both unsustainable and unsupported by the analysis in the piece. First and foremost, it portrays fraud as *consuming* science rather than merely growing alongside it. Much of the “fraud” in the paper is just metric gaming whackamole that doesn’t get read, cited or used.

Alexander Meiburg has been working on formal verification of results in quantum information. It's exciting to see a growing library of tools for formal proofs in QI github.com/Timeroot/Lea...

New preprint! Really excited about this. It's some of my best work ever, IMO: an analytic and numerical study of the Wigner's Friend problem(s) with a specific model of the measurement process and a decohering environment. arxiv.org/abs/2507.21221

Hey mathematicians: Separate from whether you think it's possible or likely, how do you think you would be psychologically affected if there was a superhuman machine for both proposing and solving theorems? Meaning basically that, vis-a-vis mathematics, you were like a Go player after AlphaGo.

I know for sure that similarly flavoured papers were not accepted for poster presentations at earlier editions of QIP. The very presence of this paper at TQC (!!) sends a very concerning signal to newcomers imo.

We have a new preprint out on the topic of quantum position verification and non-local quantum computation (NLQC): scirate.com/arxiv/2505.2.... We are comparing different NLQC tasks and find reductions between them (in the sense of if I can do task 1, then I can do task 2 with an extra EPR pair).

I see. I think the paper by Barak, Kothari & Steurer on using SoS for quantifying “entanglement” for the BSS problem ( arxiv.org/abs/1701.06321 ) + Fazwi’s papers might be suited for something like that? Laurent’s notes are a very big overview, more or less.

Guys I was browsing through the poster sessions at TQC, and came across this paper in one of the posters, eprint.iacr.org/2024/646.pdf. Is this even serious? Isn't this supposed to be a HUGE result?

I have just launched a "Lean companion" to my textbook "Analysis I": github.com/teorth/estim... . This gives a Lean translation (or paraphrasing) of the various definitions, theorems, and exercises in the textbook into Lean. Further discussion at terrytao.wordpress.com/2025/05/31/a...

I found Monique Laurent has these excellent notes on polynomial optimization, homepages.cwi.nl/~monique/fil... Maybe helpful to few QI peeps.

if i am going to survive the post economy world i am going to have to finally knit a second sock. i have no other skills. imagine deriving maxwell's equations as a possible trade for shampoo.

The arXiv looks like a minefield on April 1st - you're double guessing every title. Is "Doeblin coefficient" a real thing or made up, @markwilde.bsky.social? arxiv.org/abs/2503.22823

In quantum industry, every day is April fools!

I have disproven the Eigenstate Thermalisation Hypothesis. Turns out, most quantum systems evolve such that expectation values for most observables look like those of a state I have just written down. I will not share it. It is mine. Mine, mine, mine!
