which is a year old and basically says "more work is needed to rule out mundane sources of error like thermal expansion".
If there was a new published paper anywhere, it would be significant but there isn't. This is just a work in progress with any number of corrections to be made (NOTE: in 12 months, no one has submitted this leaked paper).
Even if it does work, it's less propulsion than an ion drive.
