Einstein’s spooky action at a distance in space.

 

A pair of entangled photons would be generated on the Earth. One of these would then be sent to a detector aboard the International Space Station, while the other photon would be measured locally on the ground for comparison.

 

Interesting. As entanglement is generally a free-space transmission experiment (going through fiber causes problems, since there are polarization effects on dispersion and loss; people are investigating if this can done), going up has its advantages — much less atmosphere, on average.
