In a recent letter [H.F. Wang, X. Ji, and S. Zhang, Phys. Lett. A 358 (2006) 11], an improvement of the multiparty quantum secret splitting and quantum state sharing protocol [F.G. Deng, et al., Phys ...
An efficient multiparty quantum secret sharing scheme is proposed, in which the secret is a quantum state , and the dealer encodes the secret by performing the operations of quantum -controlled ...
-and-resend attack. It may be still secure even if the distributed quantum state is embedded in a not-so-weak coherent- state pulse. CHIN.PHYS.LETT. Vol. 25, No. 1 (2008) 16 Multiparty Quantum Secret Sharing ...
on the pure entangled quantum state shared among dealer and all agents, the dealer’s secret quantum information, i.e., single-qubit state (or single-qutrit state ) is split in such a way that it can ...
We consider two simple and practical protocols for multiparty communication and show their experimental realization. These protocols deal with the task of secret sharing in which a secret message ...
The existing secret sharing schemes of sharing quantum information usually require the resource of entanglements no matter they are based on quantum teleportation or remote state preparation. However ...
We present a three-party quantum single-qutrit- state sharing scheme with a non-maximally entangled three-qutrit state as the quantum channel. In the scheme, the sender’s secret quantum information ...
Yuan et al. (Int. J. Theor. Phys. 51:3443, 2012) proposed a multiparty quantum secret sharing protocol using Bell states and continuous variable operations. Zhang and Qin (Int. J. Theor. Phys. 52 ...
We present a new protocol for the quantum secretsharing (QSS) task among multiparties with two-particle entangled states . In ourscheme, the secret is split among a number of participating partners ...
Multiparty remote state preparation (MRSP) is a procedure for multiparty collaboration with each other for remote preparation of a known quantum state to a distant party. We show that it is possible ...
