PT Journal AU Esteban, E Serna, H TI Quantum key distribution protocol with private-public key SO arXiv JI arXiv PY 2009 BP 3 DE quantum cryptography; QKD; protocol AB A quantum cryptographic protocol based in public key cryptography combinations and private key cryptography is presented. Unlike the BB84 protocol 1 and its many variants 2,3 two quantum channels are used. The present research does not make reconciliation mechanisms of information to derive the key. A three related system of key distribution are described. ER
