Secure Quantum Carriers for Quantum State Sharing
نویسنده
چکیده
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 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.

متن کاملQuantum secret sharing based on a reusable Greenberger - Horne - Zeilinger states as secure carriers ”
We show that the criticism of a recent comment [1] on the insecurity of a quantum secret sharing protocol proposed in [2] is based on a misconception about the meaning of security and hence is invalid. The same misconception also appears in another comment of the authors [3] on the security of an entangled-based quantum key distribution protocol [4, 5].
