WebbQuantum cryptography was first proposed by Stephen Weisner in his work "Conjugate Coding" in the early 1970s. The proposal was published in 1983 in Sigact News, and by that time two scientists Bennet and Brassard, who were familiar with Weisner's ideas, were ready to publish their own ideas. Cryptography, the use of codes and ciphers to protect secrets, began thousands of years ago. Until recent decades, it has been the story of what might be called classical cryptography — that is, of methods of encryption that use pen and paper, or perhaps simple mechanical aids.
