An interesting result to be sure, but usually constant factors don't matter that much experimentally and pi is approximately equal to one for any large n. Am I wrong about this? What's the size of n in a typical measurement, are we talking on the order of 10s or thousands or millions?
- ChrisLomont 7y ago>but usually constant factors don't matter that much experimentally and pi is approximately equal to one for any large n Not sure if you're joking, but this is not pi+n, in which case it doesn't matter as much, but pi/n, limiting the the edge of knowability of mutually measurable non-commuting observables by a factor of 3 in a direction against what we would like. And as the article mentions, experiments are within 56% of this, so they are about to hit hard limits if the math is correct. So it most certainly matters experimentally. There are many places this will affect the current edge (and future) of technology (also, as mentioned in the article). Basically it put behind an impossibility theorem things people had expected to use in technology.
