TOKYO -- Toshiba has achieved what it calls the world's first use of quantum cryptography to transmit genome sequence data, a crucial step toward commercial use of this theoretically impenetrable encryption method.

Genome data about individuals is treated as protected personal information in certain circumstances under Japanese law and is transported physically in a biometric hard drive using a fingerprint scanner. Quantum encryption allowed it to be transmitted over fiber-optic cables.
