New arXiv preprint: we show algorithmic versions of the polynomial Freiman–Ruzsa (PFR) theorem of Gowers, Green, Manners, and Tao. Interestingly, our proof draws on quantum information and stabilizer learning algorithms, which we dequantize into classical algorithms.

Hirahara, Illango, and Loff posted on the arXiv a lovely result, showing that determining the communication complexity of a function f is NP-hard. A fundamental question first asked by Yao in '79. The proof is very clean and elegant. A fun read for the weekend!

This is such a good one-sentence (albeit a long one…) explanation of quantum computing!
This!
I like to say,
"Let p|A denote distribution p conditioned on event A.
Imagine a world where the laws of probability are the same, except (p|A)|B need not equal (p|B)|A.
Except you don't have to imagine, because it's literally our world!
Now explore probabilistic algorithms in this world."

Antonina's lectures are great, and I was surprised how much I learned from Richard's lectures on Quantum Complexity theory (since I work on the field). I strongly recommend them

I am very much looking forward to giving this talk at TCS+, which is one of my favourite seminars. Thanks for inviting me!
I am very excited about this talk: First, Zero-Knowledge proofs are basically magic. Second, PCPs are nothing short of sorcery. Third, Tom is too good at everything not to secretly be a wizard.
It's going to be awesome!
