In this manuscript, a composite channel model for quantum key distribution is considered, including both a "hard output" quantum channel and a "soft output" classic channel. The metrics derived from the two channels are jointly processed at the receiver, exploiting capacity achieving soft-metric based iteratively decoded block codes, and soft-information based information reconciliation and privacy amplification techniques are proposed. The performance of the proposed mixed-soft-metric algorithms is analyzed as a function of the system parameters.
