    "abstract": "We present a three-stage quantum cryptographic protocol guaranteeing security\nin which each party uses its own secret key. Unlike the BB84 protocol, where\nthe qubits are transmitted in only one direction and classical information\nexchanged thereafter, the communication in the proposed protocol remains\nquantum in each stage. A related system of key distribution is also described.",
