You should use Signal. Seriously. There are other encrypted messaging apps out there, but I don’t have as much faith in their longevity. In particular I have major concerns about the sustainability of for-profit apps in our new “AI” world.

If you're in the EU and you're not ready to delete your facebook account for whatever reason (I feel you—I *wish* I could get rid of mine), then this is hopefully a path to at least not have your face stored forever in the mind of their new Meta AI system: reddit.com/r/facebook/commen…

Happy to announce that I am one of the winners of the recently-announced Best Slides Award at @IACReurocrypt 2024 (... affiliated events)! Check out the list other winners too—it's an entertaining read🔥🧙‍♂️

Had a chat with these awesome guys the other day about Chen's LWE algorithm. (Fun fact, the news about the bug in step 9 dropped only 15 minutes before the interview!) #eprint555
A preprint dropped couple weeks ago *almost* broke Post-Quantum Cryptography (PQC) and got everyone in the quantum & crypto communities excited! In this video, let's see what this is all about, with an awesome interview w/ PQC expert Dr. @Heum! (1/5)

Thomas Vidick wrote more thought about the bug in #eprint555 on the Discord (like Yilei, he does not appear to use Twitter).
We are back to Cryptomania until further notice. #eprint555

it's so over
Chen’s paper has a bug, independently discovered by Hongxun Weng and Thomas Vidick, that he doesn’t know how to fix. If I understand correctly, in its current form the paper doesn’t yield any improvement on prior algorithms. eprint.iacr.org/2024/555

So, iacr.eprint.org/555 happened, and now we're a bunch of people trying to scramble through 60 pages of equations. Lattice cryptanalysists typically don't know enough quantum to understand it; for others (like me) it's the opposite. Let's join forces! discord.gg/Bknnr2Aw

some more people who (or whose students) might be interested: @martinralbrecht @matthew_d_green @BordeKock @TjerandSilde @regevlab @caicocid @ASchtlr, also thanks to @nadiaheninger for the idea!

Dear University staff, reducing departmental costs and saving you time is important to us. That's why we insist you use a travel booking system that overcharges us and operates less effectively for you than a basic google search.

❓How to learn/train quantum circuits? Shallow quantum circuits are classically hard to simulate⚡️Despite extensive study, no efficient algorithm for learning/training them is known💀 In arxiv.org/abs/2401.10095, we show how to learn any shallow quantum circuit efficiently💡
