AI Will Eat Simulation Software (and this may be bad.)
My lab runs on simulation software. COMSOL for finite element modeling. Lumerical and Tidy3D for photonic FDTD. Sonnet and sometimes Palace for microwave circuits. We design quantum devices — mechanical resonators, superconducting circuits, photonic waveguides — and before anything gets fabricated, it gets simulated. "An hour of COMSOL can save a
Hackweek 2026: What happens when a physics lab stops research for ~two weeks
Research labs are exciting environments where we learn, discover and invent new things. But they can be weird as well. You can have someone who fabricates superconducting qubits or photonic circuits and builds systems that operate at the limits allowed by the laws of physics, but who has never written
Quantum Sensing Like a Bird
A few nights ago I was on a panel on Quantum Sensing for Defense. Preparing for this panel crystallized some ideas for me, which I think I should write down somewhere. So here it is! When we talk about "quantum sensing," we often imagine a single, exquisite, hyper-sensitive
Les Houches lecture notes
Spending a few days at Les Houches workshop on TFLN photonics 😄 Here are my lecture notes. These are currently a very rough draft, though fairly respectable looking... I used Gemini 2.5 pretty heavily to help prepare these notes. For example, I'd write up some notes on paper,
