Toshiba is creating a ‘foolproof’ Quantum Cryptography System that uses photons sent over a custom-made fiber optic cable that is not connected to the Internet. The firm will begin verification testing with the transmission of genome analysis data in Japan on 31 August, assisting Japan’s Tohoku University to transmit genetic data. The company believes to first provide the service to governments and enterprises, and then to consumers, when the cost of development drops. If this experiment turns out to be successful, longer-term commercial use would be possible.
