100% agree. Especially since we have author IDs that are matched to the papers when they are claimed!
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

Has quantum advantage been achieved?
Recently, I gave a couple of perspective talks on quantum advantage, one at the annual retreat of the CIQC and one at a recent KITP programme. I started off by polling the audience on who believed …

I just received a paper for a Springer journal that was obviously LLM-generated, complete with non-existent theorems, missing proofs, and hallucinated references. The journal has double-blind review. You see the problem? Stone thrown, hand hidden. No one to name-shame.

Some statistical features of Haar unitaries can be well approximated in log depth, exponentially faster than previously thought. We give evidence that this is a 'truly quantum' effect by deriving linear lower bounds for orthogonal, Clifford, symplectic, matchgate groups
