Physicists demonstrate first metro-area quantum computer network in Boston

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.

The findings were published in Nature in collaboration with members of the Harvard Quantum Initiative alongside researchers at Amazon Web Services. To learn more: "Physicists demonstrate first metro-area quantum computer network in Boston"
