Public discussion is a useful way for quantum key distribution protocols to reveal the presence of eavesdroppers. However, to ensure better security, nearly 50 of the transmitted qubits are spent in public discussions. Consequently, the original EPR quantum key distribution protocol provides only 25 qubit efficiency and Deng et al.'s scheme delivers only 50 qubit efficiency. By bringing classical cryptographic techniques into the quantum arena, this work proposes EPR quantum key distribution protocols with a potential of 100 qubit efficiency.
