摘      要：We present a(t,n)threshold multiparty controlled quantum teleportation protocol of an arbitrary m-qubitquantum state between two remote *** unknown m-qubit quantum state can be recovered by the receiver undercontrol of a subset of the n controllers if the number of the subset is larger than or equal to a threshold,say,t,but not forany t —1 or fewer *** scheme seems to be more practical and more flexible than other existing *** resource required is just m Einstein-Podolsky-Rosen(EPR)pairs plus some single *** techniquesrequired are only Bell state measurement,single-qubit unitary operation and von Neumann *** our schemeis also feasible with present-day technique.
