Abstract :
This paper describes the family of quantum protocols. The basic protocols are naturally organized into mutually dual hierarchies. A noiseless qubit channel, noiseless classical bit channel and pure ebit (EPR pair) reflect their classical-quantum and dynamic-static nature. In addition to teleportation (TP) and super-dense coding (SD), third noiseless resource inequality (RI), "entanglement distribution" (ED) are implemented through the qubit channel. Proving the existence of protocols implementing the parent RIs relies on making the existing children protocols coherent and using the technique of coherent communication.
