“…Moreover, it is worth mentioning that due to all information being apportioned to one sender, there could be leakage in information (suppose Alice is not sincere) which could lead to precarious protocol. To overcome this challenge, Xia et al [14] proposed joint remote state preparation (JRSP) where there are two parties to prepare the state for the remote receiver.…”

We present a scheme for joint remote state preparation (JRSP) of three-particle state via three tripartite Greenberger-Horne-Zeilinger (GHZ) entangled states as the quantum channel linking the parties. We use eight-qubit mutually orthogonal basis vector as measurement point of departure. The likelihood of success for this scheme has been found to be 1/8. However, by putting some special cases into consideration, the chances can be ameliorated to 1/4 and 1. The effects of amplitude-damping noise, phase-damping noise and depolarizing noise on this scheme have been scrutinized and the analytical derivations of fidelities for the quantum noisy channels have been presented. We found that for 0.55 ≤ η ≤ 1, the states conveyed through depolarizing channel lose more information than phase-damping channel while the information loss through amplitude damping channel is most minimal. Keywords IntroductionWhen a pair of particles is generated such that the quantum state of each particle cannot be elucidated independently, we referred to them as being entangled. One of the effortless ways to create entanglement is using a very powerful laser along with some very special crystals in order to entangle pair of photons which are the smallest unit of light. Experimental realization of quantum entanglement has been achieved and presented more elaborately in reference [1]. Quantum entanglement represents basic ingredient in quantum information processing.

Entanglement has been found resourceful in quantum state sharing [2]. Information stored in quantum system can be teleported from one location to the other with the aid of shared entangled state [3]. Some other processes that exploit quantum entanglement include quantum dense coding [4], quantum secure direct communication [5] and remote state preparation (RSP) [6].The quantum teleportation can be described as a process by which quantum information is being transmitted from one location to another, with the aid of classical communication and erstwhile shared quantum entanglement between the sending and receiving location. In quantum teleportation, the sender has a particle of unknown state. Whereas, in RSP, the sender does not own the particle

“…After that, many researchers studied and proposed different theoretical types of RSP [17][18][19][20][21][22][23][24] . On the other hand, Peng et al [19] have implement RSP using Nuclear magnetic resonance and Xiang et al [21] have implemented RSP using spontaneous parametric down-conversion, single photon detector and linear optical elements.…”

Abstract-In this paper we propose a new algorithm for secret key sharing by utilizing quantum entanglement swapping and remote preparation of quantum state. This algorithm is used when two parties do not share an Einstein-Podolsky-Rosen (EPR) pair but one wishes to transmit a secret key to the other. In order to successfully accomplish this process, a third party who shares an EPR pair with both parties will help them build a new EPR pair. The new EPR pair will be used between the sender and the receiver to remotely prepare a quantum state. This process will provide a secure way to share secret keys between the two parties who do not share EPR pairs. Furthermore, the process doesn't require sending any physical quantum state, instead the sender prepares a known state and sends only one classical bit to the receiver to help build an intended quantum state.

“…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.…”

“…Then conditioned on the measurement results on the auxiliary qubits, the receiver performs an appropriate unitary operations on the eligible state to properly retrieve the prepared state. Note that, the so-called proper measurements are projective measurements in the latter type of existing RSP schemes [39][40][41][42]. As a matter of fact, there lies another type of measurement named positive operator-valued measure (POVM) [43], which was also called generalized measurement [44].…”

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.
