Light Particles Are Duplicated More Than a Mile Away Along Fiber: ‘Employing a facet of quantum mechanics that Albert Einstein called “spooky action at a distance,” scientists have taken particles of light, destroyed them and then resurrected copies more than a mile away.

Previous experiments in so-called quantum teleportation moved particles of light about a yard. The findings could aid the sending of unbreakable coded messages, which is limited to a few tens of miles.

The new experiment used longer wavelengths of light than earlier ones, letting the scientists copy the light through standard glass fiber found in fiber optic cables.’ NY Times
