New on arXiv: we show algorithmic versions of the polynomial Freiman–Ruzsa theorem of Gowers, Green, Manners, and Tao. Interestingly, our proof draws on quantum information and stabilizer learning algorithms, which we dequantize into classical algorithms. arxiv.org/pdf/2509.02338

We’re excited to propose and validate simple methods for preparing ground states and thermal states of many-particle quantum systems, which might be feasible for early fault-tolerant quantum devices. All the credit goes to my brilliant collaborators. arxiv.org/abs/2508.05703

A new #quantum logic gate enables a family of high-rate quantum low-density-parity-check, or qLDPC, codes to measure logical #qubits selectively and in parallel, opening avenues for spacetime-efficient, fault-tolerant quantum computation. Read the paper: go.aps.org/4kvwsaa

Great to see momentum building around quantum LDPC codes. This [[18,4,4]] demo on Kunlun is a solid proof of principle—but still a gadget in my view. Offline BP-OSD, air bridges, small code. Not scalable, but a step. More on our scalable approach coming soon.…

*How much advantage can entangled quantum sensors give over unentangled sensors?* Conventionally entanglement is thought to give, at best, a quadratic advantage in quantum sensing: Heisenberg (1/N) vs Standard-Quantum-Limit (1/Sqrt(N)) scaling. 1/

Are random circuits useful in anything other than sampling? With @henryquantum and others, we suggest the answer is yes. We lay out NISQ-friendly quantum cryptographic schemes with random circuits. 😃 @UChicagoCS @Columbia @UofIllinois scirate.com/arxiv/2504.153… 1/5 📜

Do abstract learning processes have tangible physical consequences? Yes! In this work, we rigorously show that the (in)ability to learn dramatically impacts the amount of physical resources required to perform certain thermodynamic tasks. arxiv.org/abs/2504.07341
