New paper with @MCrichigno at @Phasecraft. AI agents optimize quantum circuits, and an exact verifier checks every result. arxiv.org/abs/2610.31352
The challenge itself is automated too. An agent works with a researcher to build the verifier, tests it, and freezes it. Then the agents compete.
We observed large gains on every problem we tried, from fermion-to-qubit encodings to qubit routing and unitary synthesis. The method applies to any problem with an exact checker.
It's great to see others working in the same direction this week. Excellent papers from Google Quantum AI and Harvard/QuEra/Anthropic:
arxiv.org/abs/2610.23832
arxiv.org/abs/2610.22367
and the inverse square root challenge:

New paper out!! 🥳😄
Last Friday we uploaded our latest preprint to the arXiv:
"The commutant of fermionic Gaussian unitaries"
Amazing collaboration with @TheImPolster @Nahuel_L_Diaz @MartinLaroo and @DiegoGM_quantum !

Human insight is still a thing: over the last few years many computing resources were thrown towards the Merzon-Smirnov conjecture on maximal Schubert polynomials, including DeepMind's FunSearch. In the end it fell to a human-generated targeted check: arxiv.org/abs/2603.20104

Theorists at @IBMResearch uncover a new quantum algorithm demonstrating a substantial speedup over the best classical methods—and showing what the process of algorithm discovery looks like. ibm.co/6011BzS05
ALT Quantum algorithm discovery is the key to unlocking quantum computing’s full potential. A team of IBM researchers make a breakthrough by applying group theory—a mathematical framework deeply intertwined with quantum physics—to design a novel quantum algorithm.

I am so, so happy to see this article published as a perspective in Nature Communications:

More than the paper itself, I thoroughly enjoyed chatting with all my co-authors on the implications of the absence of BPs ~ classical simulability connection

🚨Excited to share our new paper Characterizing quantum resourcefulness via group-Fourier decompositions from last year's LANL Quantum Computing summer School📘 arxiv.org/abs/2506.19696 !
Martin Larocca retweeted
This is an extremely cool paper from our summer school! If you missed it, and want the tldr, LANL recently put out a press release on our work!!
lanl.gov/media/news/0528-qua…
Again, huge props to my co authors @alicewithoutbob, @sornborg @MartinLaroo @DiegoGM_quantum!
Can I interest you in a new BQP-complete problem? It's about huge interferometers.
Proud to see our paper published in PRL!

New paper out, directly by the @LosAlamosNatLab summer school!
We analyze classical shadows with respect to the orthogonal group (or real Cliffords), and find that it can be advantageous over the full unitary case in various situations for real observables. 🎲⚛️

Are you interested in Quantum Convolutional Neural Networks?
What if they were indeed… classically simulable?
