NEC extends quantum cryptography range and speed
NEC researchers have developed a quantum cryptography system with sufficient speed and range to make it commercially viable. It could go on sale in the second half of 2005.
The system can generate quantum keys at a speed of 100k bps (bits per second) and transmit them over distances of up to 40 kilometers along commercial fiber optic lines. This combination of speed and distance is a world record, and means the system is suitable for commercial use, according to Kazuo Nakamura, senior manager of NEC's quantum information technology group at the company's Fundamental and Environmental Research Laboratories.
