Apparently “entangled light” was found to be travelling 10,000 times faster than the speed of light, the ultimate speed limit in the universe, in a recent Swiss experiment:
The idea in the new experiment is that the photons in each entangled pair are hitting the distant detectors simultaneously, so there’s no time for them to exchange a signal. By comparing results from the two detectors, the researchers determined whether the photons were entangled or not, using a test known as Bell’s inequalities. The photons were indeed entangled, the group reports in Nature. But in reality, no experiment is perfect, so what they end up with is a lower limit on how fast the entanglement could be traveling: 10,000 times the speed of light.
