Entanlged Vs Unentangled Based Alternative Quantum Cryptography

In alternative unentangled based cryptosystem, classical channel can not be used when the system is protected by no-cloning principle. But for the similar security criteria , it is shown that classical channel can be used in alternative entangled based quantum cryptosystem. A prototype of conventional entangled based cryptosystem is recovered from alternative entangled based cryptosystem, but such recovery is not possible from alternative un-entangled based cryptosystem. We conclude that entangled based cryptosystem is superior than un-entangled based system.
