Joint remote state preparation via W and W-type states

Nguyen Ba An

New protocols for joint remote preparation of single- and two-qubit states using Wand W-type states as the quantum channel are proposed. It is shown that, independent of entanglement degree of the shared quantum channel, the protocols succeed with any unequipped receiver by superior's judicious splitting of the information identifying the state to be prepared.
