Quantum 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 with Graph States
We study the graph-state-based quantum secret sharing protocols [24, 17] which are not only very promising in terms of physical implementation, but also resource efficient since every player’s share is composed of a single qubit. The threshold of a graph-state-based protocol admits a lower bound: for any graph of order n, the threshold of the corresponding n-player protocol is at least 0.506n. ...
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].
متن کاملMultiparty quantum secret sharing of secure direct communication
Based on the two-step protocol [Phys. Rev. A68(03)042317], we propose a (n, n)-threshold multiparty quantum secret sharing protocol of secure direct communication. In our protocol only all the sharers collaborate can the sender’s secure direct communication message be extracted. We show a variant version of this protocol based on the variant two-step protocol. This variant version can considera...
