alt Hacker NewsMostly what I was able to read from the papers seemed to work. There were some remaining issues related to detector non-equivalence (I think) that appear to be solved with a temperature stabilized detector or very strongly attenuating the beam; the latter isn't ideal as it reduces the signal to noise.
It's interesting how fast such experiments usually run into the laws of physics. I'm trying something along those lines myself and I've found myself wishing daily that light traveled a bit slower. I see Discworld in a wholly different light ;)
