A mighty little light particle has jogged (read: teleported?) its first quantum marathon around the universal hub in a groundbreaking new scientific study. Harvard phsyicists used existing Boston-area telecommunication fiber networks to send the particle over a roughly 22-mile loop through Cambridge, Somerville, Watertown, and Boston between two quantum computers located a floor apart in Harvard labs.

Think of it as a simple, closed internet between point A and B, carrying a signal encoded not by classical bits like the existing internet, but by perfectly secure, individual particles of light.
