It may be the combination is new; I don't know the exact state of the field, but: This experiment uses a single photon, so they don't have to sample multiple times and make a statistical analysis on that part. If they did, that might open the efficiency loophole. The communication loophole isn't opened, as they are in sufficiently distant labs, with short enough measurement frames, but that's been done before.
As far as I can tell, the disjoint measurement loophole doesn't apply here, either, as it opens when correlations are drawn from multiple samples; here there's one. I'm not sufficiently expert to tell whether the rotational invariane, or other loopholes are closed here. Can anyone shed some light on this?
