Spooky Experiments Bring Quantum Weirdness To Nearly Macroscopic Scales

Experimenters around the world are trying to harness perhaps the most perplexing property in physics: Quantum entanglement, which Einstein called “spooky action at a distance”. A few teams of scientists have succeeded in bringing this eerie behaviour, which normally only exists between pairs of particles, to much bigger systems.

A New Way Of Thinking About Spacetime That Turns Everything Inside Out

One of the weirdest aspects of quantum mechanisms is entanglement, because two entangled particles affecting each other across vast distances seems to violate a fundamental principle of physics called locality: things that happen at a particular point in space can only influence the points closest to it. But what if…
