You can do about 5x worse (in accuracy terms) than a Cesium clock in a smaller package using a rubidium atomic clock. Average ~4 of these and you get to the same accuracy as a cesium clock. They aren't export controlled because they aren't that special in terms of what you get.
- mapt 2y agoTo improve instrumental accuracy by 5x in a single dimension when fighting against random uncorrelated drift/noise, from what I recall of statistics you require 5^2 = 25x as many instruments.
- pclmulqdq 2y agoYeah, I think you're actually right. I was thinking you double them with 2 (experimentally), so you double that again to get 4x, but my curve was pretty off.
