I'm honored that this work with David Gosset and Chenyi Zhang was selected as one of three long plenary talks at QIP 2026!

A very clear, detailed talk by Kewen Wu on our joint work with @booleananalysis.bsky.social

Are you a computer scientist and don't know what an OTOC is, but want to understand the problem solved in the recent Nature paper by Google Quantum AI? We wrote a 2-page note that explains the motivation and presents a simplified version of the problem for any input size.

Are you a PhD student in quantum computing and interested in working with our team in 2026 as a student researcher (i.e., an internship that's ~3 months and in-person at our office)? If so, apply here:

Fresh on the arXiv: @booleananalysis.bsky.social, Kewen Wu, and I present new classical algorithms for the Short Integer Solution problem (under infinity norm) that outperform the elegant Chen-Liu-Zhandry quantum algorithm, showing that there is no exponential quantum speed up anymore.

New paper on the arXiv with David Gosset and Google student researcher Chenyi Zhang on how to implement an n-qubit Toffoli gate (approximately) with exponentially fewer T gates than previously thought.

The notifications for #FOCS2025 are out: congratulations to all!

The registration page is up: focs.computer.org/2025/register/
and information about student travel support will be added within days.

Looking forward to seeing you in Sydney in December!

In "On the Rational Degree of Boolean Functions and Applications" with Vishnu Iyer, Siddhartha Jain (@sidjai.bsky.social), Matt Kovacs-Deak, Vinayak Kumar, Luke Schaeffer, Daochen Wang, and Michael Whitmeyer, we prove many interesting results about rational degree.

The submission server for #FOCS2025 is now open! Submit your work: focs25.hotcrp.com

Some #qip2025 talks this week by my excellent student coauthors:

Mon 1:30pm (Kewen Wu): Quantum state preparation with optimal T-Count

Mon 5pm (Alexander Schmidhuber): Quartic quantum speedups for planted inference

Fri 5pm (Robbie King): Triply Efficient Shadow Tomography

If you're an early-career faculty member (received their PhD within seven years of submission) in quantum computing, consider applying to Google's Research Scholar Program. The application process is lightweight and the grant comes in the form of an unrestricted gift.
