Arxiv's lack of commitment to its author page feature is so disappointing. Why, when I click on the link that is an author's name, am I sent to a search page of "F. Lastname"? This is ridiculous

Absolutely maximally entangled pure states of multipartite quantum systems
https://arxiv.org/abs/2508.04777
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.
