Quantum cryptography on the xo laptop (24C3)

[Chris Hager]

Hey folks, crazy news:

On Saturday 29.12.07, there was a successful 'entanglement based quantum 
key distribution' between two xo-laptops!!

QKD is a quantum-cryptographic scheme to securely distribute correlated 
random numbers between the communicating parties.

At the 24C3, we (sj and aaron, chris, tano from olpc-austria) met people 
from the National University of Singapore, which brought the hardware of 
a full working kit for entanglement based QKD over a free space channel. 
They got interested on the xo, started playing with 2 of the laptops, 
and finally had success exchangig the keys between two xo laptops.
