| 摘 要： | We present a scheme for probabilistic remote preparation of an entangled two-qubit state with three parties from a sender to either of two receivers. The quantum channel is composed of a paxtially entangled two-qubit state and a partially entangled three-qubit state. We calculate the successful total probabilities of the scheme in general and particular cases, respectively. We also calculate total classical communication cost in a general case and two particular cases, respectively.

| Abstract: | We present a scheme for probabilistic remote preparation of an
entangled two-qubit state with three parties from a sender to either
of two receivers. The quantum channel is composed of a partially
entangled two-qubit state and a partially entangled three-qubit
state. We calculate the successful total probabilities of the scheme
in general and particular cases, respectively. We also calculate
total classical communication cost in a general case and two
particular cases, respectively. |
