ATMOSPHERIC turbulence can be a pain for plane passengers, but for entangled photons it could prove something of a boon. The particles used in quantum cryptography communication travel like a dream through a turbulent atmosphere.
In 2007, Anton Zeilinger’s team at the University of Vienna, Austria, created entangled pairs of photons on a mountain top in La Palma, one of the Canary Islands, and beamed one of each pair 144 kilometres through the air to Tenerife, establishing the longest ever quantum communications channel.
We have yet to tease out all…
