Garbage In, Garbage Out: Atomic-Photon Breakthrough
Will Knight writes in NewScientist:
A trick for transferring quantum information from atoms to photons and back again could be used to create impenetrable global communication networks and computers that work at astounding speeds.
Two research groups, one led by Mikail Lukin at Harvard University and the second headed by Alex Kuzmich of Georgia Institute of Technology, both in the US, separately demonstrated the feat using similar methods.
Both teams employed powerful laser pulses to extract quantum information from a cloud of atoms in the form of a single photon. That photon was then transmitted through a normal optical fibre before its quantum state was transferred to a second atomic cloud.
