Scientists have teleported quantum information between two bits of diamond located 10 feet apart. It's a prime example of "spooky action at a distance" — and an achievement that could lead to quantum networks exponentially more powerful and secure than today's supercomputers.

New research on wormholes suggests that these theoretical shortcuts that connect distant points in the universe might be linked with the spooky phenomenon of quantum entanglement. As Charles Q. Choi writes in LiveScience, this would allow particles to be connected regardless of how far apart they are — a finding that…
