While messing around with numerical models of entangled states, I found a very simple and convenient way to characterize entanglement without a local frame of reference:

It's the one result from my academic career that really felt rewarding. It's not a very important or mind-blowing result, but it is vaguely useful, and (to me at least) enlightening, and it is a clean, finished, self-contained piece of work. Makes me happy at least :)
- jiffyjeff 3y agoHoly cow, this might be related to a design I had last week. My effort to build optical shaft encoders using simple polarization sheet. LEDs can be be used as bidirectional sensors as they work well as photodiodes. That lends itself to optical ring oscillators. Getting them synchronized across multiple encoders and/or controllers led to a control scheme that was.. interesting.
