This small device developed at Los Alamos National Laboratory uses the truly random spin of light particles as defined by laws of quantum mechanics to generate a random number for use in a cryptographic key that can be used to securely transmit information between two parties.

Quantum key distribution represents a foolproof cryptography method that may now become available to the general public, thanks to a licensing agreement between Los Alamos and Whitewood Encryption Systems, LLC. Los Alamos scientists developed their particular method after two decades of rigorous testing.

Quantum key distribution technology could ensure truly secure commerce, banking, communications and data transfer.
