In a new paper with @abaysmidt.bsky.social and @nqcp-nbi.bsky.social, we propose quantum simulation of nanographenes as an application to bridge early and later fault-tolerant quantum computing and study Trotter errors. scirate.com/arxiv/2605.0...

Quantum simulation of nanographenes and Trotter error cancellation
Fault-tolerant quantum computing is a promising tool for simulating molecules and materials, but frequently-considered applications require substantial resources, and the gap between hardware capabili...

I'm often asked if I'll redo the 2019 quantum factoring estimate. Denser storage by yokes, smaller magic factories by cultivation, slimmer approx arithmetic by Chevignard et al… surely the cost is lower now? Yes, it's lower now. security.googleblog.com/2025/05/trac... arxiv.org/abs/2505.15917

Arrived in LA. Stuck in traffic on way to hotel, of course. Good flights. Read some papers with a longer update coming soon. Movie: the Dracula remake. Very much liked. Only seen bits of the original but could tell there were a lot of references. Very dark and gritty. 5 stars.
