How fast do quantum interactions happen? Faster than light, 10,000 times faster.
That's what a team of physicists led by Juan Yin at the University of Science and Technology
of China in Shanghai found in an experiment involving entangled photons,
or photons that remain intimately connected, even when separated by
vast distances.They wanted to see what would happen if you tried
assigning a speed to what Einstein called "spooky action at a distance."They didn't find anything unexpected, but that wasn't the point: in physics, sometimes it's good to be sure. The group published their work on the ArXiv.org, a preprint server
for physics papers.
