Quantum Sensing
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
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,

Quantum Sensing
What about those time-energy and number-phase uncertainty relations? The way the time-energy uncertainty was often explained to me when I first learned quantum mechanics felt pretty hand-wavy ... The QCRB solves this and puts these uncertainty relations on a proper footing.
