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.

It took me a while, but I (finally) wrote a "short" (erm) note on the "polynomial+moments method" to prove testing or indistinguishability sample complexity lower bounds. Including the infamous Ω(k/log k) tolerant uniformity testing one. Comments and feedback welcome! 📝

What is the min depth you need for a random unitary? In this work w/ Tommy Schuster, @RobertHuangHY, Fernando Brandão (
arxiv.org/abs/2507.06216
) we glue random unitary blocks w/ only random phases on log n qubits (fns on log n bits) to get designs in d = log k log log n 🧩 1/8

One of the amazing things about working in quantum information science is being able to meet and talk to the pioneers of the subject. I was very lucky not only to have met Ray, but also to have been a postdoc in his group for a number of years.

🪇Disambiguating Pauli noise in quantum computers
scirate.com/arxiv/2505.2...
Quantum noise characterization suffers from "gauge ambiguity" due to noisy initialization and measurements. We show this does not stop us from correctly mitigating errors, both in theory and in up to 92-qubit experiments

Why characterise noise in syndrome extraction circuits? One reason: directly improving quantum error correction! In simulations of the surface code, we find that noise-aware decoding—calibrating the decoder with noise estimates—improves the code's error suppression factor.

If qubits only talk to 1D neighbors, is constant rate fault tolerance possible? Last year I referee'd a paper claiming it wasn't. My review was "this is wrong but the constructive disproof is too large for this review". Clearly a reviewer 2 move. Sorry. But I was right!

I'm thrilled to announce my latest work with Marcus Appleby and Gene Kopp,
scirate.com/arxiv/2501.0...

A Constructive Approach to Zauner's Conjecture via the Stark Conjectures
We propose a construction of $d^2$ complex equiangular lines in $\mathbb{C}^d$, also known as SICPOVMs, which were conjectured by Zauner to exist for all d. The construction gives a putatively complet...
