“…We notice that the total success probability will approach to 1.0 when the parameters satisfy a ≈ b ≈ 1 √ 2 , c ≈ 0 and r ≈ s ≈ 1 √ 2 , t ≈ 0. In fact, this case is equivalent to the case of the RSP scheme via two EPR states discussed in [20]. By similar analyses, we deduce that these specially chosen initial states to be prepared remotely can also be reestablished at Carol's side with the total success probability 4(ct) 2 .…”

“…Owing to its distinct feature, RSP has attracted extensive attention and various schemes for RSP have been reported in succession [4,[16][17][18][19][20]. As we know, most of the previous schemes for RSP discuss the quantum state which is transmitted from one sender to one receiver [4,18,19], and few of them apply the method of the positive operator-valued measurement (POVM) to remotely prepare a two-particle entangled state.…”

We present a scheme for remotely preparing a general two-particle entangled state via two tripartite W entangled states of different amplitudes. In this scheme one sender and two remote receivers are involved. The sender can help either one of the receivers to remotely reconstruct the original state with the aid of the other receiver's two single-particle orthogonal measurements. It is shown that by means of the method of the positive operatorvalued measurement, our remote state preparation scheme can be achieved probabilistically.Keywords Remote state preparation · W state · Positive operator-valued measurement Entanglement, a new class of correlations between quantum systems making quantum information different from classical information in nature, is a fundamental conception in quantum mechanics and quantum information theory. It has provided a new physical resource for quantum information processing such as quantum teleportation [1], quantum cryptography [2], remote state preparation [3][4][5][6][7][8], quantum computation [9] and so on. As to tripartite quantum pure states, there are only two nonequivalent classes, the Greenberger-Horne-Zeilinger (GHZ) class and the W class [10,11], under stochastic local operation and classical communication. Although the properties of the tripartite entangled states have not been fully understood, the tripartite GHZ state and W state have been applied in many aspects of quantum information [12][13][14][15], including remote state preparation (RSP) which is regarded as an interesting direction of quantum information. RSP has prospered since its inception [3][4][5], and is still in rapid development. It is also called "teleportation for a known state", for its task

“…flyan@mail.hebtu.edu.cn have been implemented experimentally with the technique of NMR [16] and spontaneous parametric downconversion [17,18]. In addition, some authors have also investigated the RSP protocol using different quantum channels such as partial EPR pairs [19] and three-particle Greenberger-Horne-Zeilinger (GHZ) state [20]. To our best knowledge, up to now there is no RSP protocol which determinately generate an arbitrary qubit with unit success probability.…”

We present a two-step exact remote state preparation protocol of an arbitrary qubit with the aid of a three-particle Greenberger-Horne-Zeilinger state. Generalization of this protocol for higherdimensional Hilbert space systems among three parties is also given. We show that only singleparticle von Neumann measurement, local operation and classical communication are necessary. Moreover, since the overall information of the quantum state can be divided into two different parts, which may be at different locations, this protocol may be useful in the quantum information field.

“…Also some RSP schemes are investigated by using different entangled states as quantum channel [34][35][36][37][38][39][40][41][42]. In terms of entanglements in quantum channel, these RSP schemes can be classified into two types.…”

“…In terms of entanglements in quantum channel, these RSP schemes can be classified into two types. One takes pure entangled states as the quantum channel [34][35][36][37][38] while the other utilizes partly pure entangled states [39][40][41][42]. In the latter case, usually people need to introduce one or more auxiliary qubits and then entangle them with his/her original qubits.…”

Abstract. We present a novel tripartite scheme for remotely preparing an arbitrary two-qubit state with two three-qubit entanglements. By using a proper positive operator-valued measure (POVM), it is shown that the remote two-qubit preparation can be realized in either distant ministrant's place in a probabilistic manner via their collaboration. We also explore its applications to six special ensembles of state in detail. The extensive investigations show that the remote preparation can be achieved with higher probability provided that the prepared state belongs to the six special ensembles.
