A laser beam is transmitted from La Palma
(in the horizon) towards the ESA's Optical Ground Station (OGS) in
Tenerife (part of the dome is visible on the left) during a quantum
communication test.

If secret agent James Bond wanted to tell his MI6 superiors
about the location of a stolen superweapon without tipping off villains,
he might turn to a global satellite network that transmitted coded keys
made unbreakable by the weird laws of physics. Such "quantum key
distribution" already exists on Earth beyond the realm of Hollywood spy
fantasies, and could soon head for space.
Plans to launch quantum communication satellites have already begun
to take shape in Canada, Japan and the European Union. The satellites
could securely transmit digital keys through light particles by using
physics tricks such as quantum entanglement — the phenomenon that allows two entangled particles to affect one another other even across the distance of a galaxy. MORE: http://www.msnbc.msn.com/id/46581073/ns/technology_and_science-innovation/#.T0_ye_nlsbY
