in Physics & Chemistry
Electronic communication is becoming more secure all over the world. Siemens IT Solutions and Services, Austrian Research Centers (ARC) and Graz University of Technology have joined forces to develop the first quantum cryptography chip for commercial use. The chip, which protects data by generating a completely random sequence of numbers from particles of light, replaces the currently used system of key distribution based on mathematical algorithms.
