Remote preparation of a two-particle entangled state

With two pairs of entangled particles as the quantum channel, we present a scheme for preparing remotely a two-particle two-dimensional entangled state and generalize it to higher-dimensional cases. We show remote preparation of arbitrarily dimensional equatorial entangled states can be realized with unit probability through a two-particle projective measurement. (C) 2003 Elsevier B.V.
