Direct and Reverse Secret-Key Capacities of a Quantum Channel

Direct and Reverse Secret-Key Capacities of a Quantum Channel

We define the direct and reverse secret-key capacities of a memoryless quantum channel as the optimal rates that entanglement-based quantum-key-distribution protocols can reach by using a single forward classical communication (direct reconciliation) or a single feedback classical communication (rev...
