Quantum cryptography, the only method which can provide quantifiable security of a distributed key, became the first application of quantum information methods. Complementary to fiber based systems, free space optics enables one to establish a secure key in various new scenarios,e.g., authentication to money machines or short distance links in metropolitan… CONTINUE READING
