Secure Quantum Carriers for Quantum State Sharing
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 gener...
متن کاملTripartite quantum state sharing.
We demonstrate a multipartite protocol to securely distribute and reconstruct a quantum state. A secret quantum state is encoded into a tripartite entangled state and distributed to three players. By collaborating, any two of the three players can reconstruct the state, while individual players obtain nothing. We characterize this (2,3) threshold quantum state sharing scheme in terms of fidelit...
متن کاملQuantum strongly secure ramp secret sharing
Quantum secret sharing is a scheme for encoding a quantum state (the secret) into multiple shares and distributing them among several participants. If a sufficient number of shares are put together, then the secret can be fully reconstructed. If an insufficient number of shares are put together however, no information about the secret can be revealed. In quantum ramp secret sharing, partial inf...
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].
