The odds of quantum weirdness being real just got a lot higher

The world is as weird as we feared. A new experiment confirms yet again the existence of correlations between distant entangled quantum particles – and this time we have measured the phenomenon so precisely, there is only a minuscule chance it is a fluke.

This is sometimes called “spooky action at a distance”, a phrase used by Albert Einstein in the 1930s when he protested the possibility of two entangled particles exhibiting correlated behaviours across extreme distances, appearing…
