It's worth reading the new version (either on CMP or the arXiv at arxiv.org/abs/2407.07876), since we're giving a streamlined and much more readable proof of our main result!
Approximate Unitary $k$-Designs from Shallow, Low-Communication Circuits
Random unitaries are useful in quantum information and related fields, but hard to generate with limited resources. An approximate unitary $k$-design is an ensemble of unitaries with an underlying mea...

Agree with the advantages! But when this is announced a week before the desired cut-off date, and the latter also coincides with the first day of instruction, it creates some logistical problems 🙃

Yes, Semenyo at City will be interesting to watch! Curious how many minutes he'll get... @Foden: transferred Thiago out just before he remembered how to score, and afraid the same will happen with Foden 🙈

That's awesome Richard 💪 fellow knee patient here (two ACL tears in the course of 8 years in the same knee playing ⚽). I stopped playing because of my injuries and am missing it a lot. But I'm glad to be able to stay active in other ways (running and certain exercises).
