Toshiba wants to 2020. quantum cryptography systems on the market




Toshiba will own words in 2020 bringing a ‘uncrackable’ system which applies on the market quantum cryptography. By laying fiber optic cables that do not connect to the Internet without repeaters photons can be sent to 100km.

Toshiba logo The plans of Toshiba in the field of quantum cryptography are explained done in The Wall Street Journal. A problem in the application of quantum cryptography is that the establishment of a secure connection between systems over long distances is difficult because there are no repeaters can be used. Also, the photons traveling over these compounds highly sensitive to heat and vibration.

Toshiba thinks the problem is partially solved by having to explain their own fiber connections that would not need repeaters to a maximum distance of 100km. This keeps the photons with the necessary keys and the encrypted content intact, and can be laid uncrackable compounds in theory. The fiber connections are also not connected to the Internet.

Currently, Toshiba ordered a laboratory, but in August the Japanese group wants together with the Tohoku University to do testing by transmitting data sets of genetic information via encryption technology. Toshiba hopes the first quantum cryptography systems around 2020 offer to go commercial, net name to large businesses and government agencies. The prices are still high: just the required servers cost more than 71,000 euros each.
