Quantum cryptography, a completely secure means of communication, is much closer to being used practically as researchers from Toshiba and Cambridge University’s Cavendish Laboratory have now developed high speed detectors capable of receiving information with much higher key rates, thereby able to receive more information faster.
Published as part of IOP Publishing’s New Journal of Physics’ Focus Issue on ‘Quantum Cryptography: Theory and Practice’, the journal paper, ‘Practical gigahertz quantum key distribution based on avalanche photodiodes’, details how quantum communication can be made possible without having to use cryogenic cooling and/or complicated optical setups, making it much more likely to become commercially viable soon.
One of the first practical applications to emerge from advances in the often baffling study of quantum mechanics, quantum cryptography has become the soon-to-be-reached gold standard in secure communications.
