Quantum Cryptography or Quantum key distribution (QKD) is a technique that allows the secure distribution of a bit string, used as key in cryptographic protocols. When it was note...
Turbo coding is a powerful class of error correcting codes, which can achieve performances close to the Shannon limit. The turbo principle can be applied to the problem of side-in...
