CODES FOR KEY GENERATION IN QUANTUM CRYPTOGRAPHY
Berthold‐Georg Englert, Fang‐Wei Fu, Harald Niederreiter, Chaoping Xing · 2005
As an alternative to the usual key generation by two-way communication in schemes for quantum cryptography, we consider codes for key generation by one-way communication. We study codes that could be applied to the raw key sequences that are ideally obtained in recently proposed scenarios for quantum key distribution, which can be regarded as communication through symmetric four-letter channels.
