Quantum codes stop all attempts to steal data

Two electronics groups Japan Mitsubishi and NEC have announced a big step in the application of quantum principles to secure computer information. They have for the first time successfully connected the cryptographic systems of many vendors.

Researchers at the University of Tokyo's Institute of Industrial Science were able to authenticate and ensure the two coding systems performed properly in eavesdropping experiments. With the new method, all information snooping on quantum code systems is detected. Besides, the data is also preserved when moving within 200 km but the transmission speed has not been announced.

NEC affirmed that the ability to link systems has a special meaning, because any development of quantum code for real-world commercial applications needs to be concerned about interaction.

2006 is the year when the quantum field will reap many important achievements. Last month, the Japan National Institute of Technology (NIST) said it broke the world record for the ability to transmit information via quantum code systems at a rate of 4 million bits per second over a 1 km long line. .

Quantum technology is drawing special attention from British, American and Japanese scientists. Many universities in these countries are focusing their research on the goal of building a quantum photon data transmission network and guaranteeing 100% that every intention to break data encryption will be immediately detected.
