Quantum key distribution protocols using entangled state

We present three quantum key distribution protocols using entangled state. The first protocol is based on the idea of qubit transmission in blocks. Although it needs quantum memory, its theoretic efficiency approximates to 100%. The second protocol does not need quantum memory and its efficiency for qubits can achieve 100%. The third protocol is a controlled quantum key distribution protocol which can be applied to a special cryptographic scenario
