Deterministic joint remote state preparation

We put forward a new nontrivial three-step strategy to execute joint remote state preparation via Einstein-Podolsky-Rosen pairs deterministically. At variance with all existing protocols, in ours the receiver contributes actively in both preparation and reconstruction steps, although he knows nothing about the quantum state to be prepared. -- Highlights: → Deterministic joint remote state preparation via EPR pairs is proposed. → Both general single- and two-qubit states are studied. → Differently from all existing protocols, in ours the receiver participates actively. → This is for the first time such a strategy is adopted.
