SECURE QUANTUM CARRIERS FOR QUANTUM STATE SHARING

VAHID KARIMIPOUR, MILAD MARVIAN
2012 International Journal of Quantum Information  
We develop the concept of quantum carrier and show that messages can be uploaded and downloaded from this carrier and while in transit, these messages are hidden from external agents. We explain in detail the working of the quantum carrier for different communication tasks, including quantum key distribution, classical secret and quantum state sharing among a set of n players according to general threshold schemes. The security of the protocol is discussed and it is shown that only the
more » ... t only the legitimate subsets can retrieve the secret messages, the collaboration of all the parties is needed for the continuous running of the protocol and maintaining the carrier.
