Abstract

We firstly present a novel scheme for deterministic joint remote state preparation of an arbitrary five-qubit Brown state using four Greenberg—Horme—Zeilinger (GHZ) entangled states as the quantum channel. The success probability of this scheme is up to 1, which is superior to the existing ones. Moreover, the scheme is extended to the generalized case where three-qubit and four-qubit non-maximally entangled states are taken as the quantum channel. We simultaneously employ two common methods to reconstruct the desired state. By comparing these two methods, we draw a conclusion that the first is superior to the second-optimal positive operator-valued measure only taking into account the number of auxiliary particles and the success probability.

Deterministic joint remote preparation of an arbitrary five-qubit Brown state

MengXiao Ding, Min Jiang, Xu Huang +1 more

In this paper, we propose a novel scheme for deterministic joint remote state preparation (JRSP) of an arbitrary five-qubit Brown state with the assistance of several GHZ entangled states and a two-qubit unitary operation. A useful solution of joint remote preparation of an arbitrary three-qubit state is put forward firstly. Next, all senders perform appropriate projective measurement under suitable measurement basis. Finally, based on their measurement results, the target five-qubit Brown state can be prepared by introducing two auxiliary particles and making appropriate local unitary operations with success probability 1.

Joint Remote Preparation of an Arbitrary Three-qubit State Via Generalized Bell States Channel

Yun‐Jie Xia

In this paper,a scheme for realizing a joint remote preparation of an arbitrary three-qubit state is researched.The scheme adopts generalized Bell states as quantum channels,each preparer measures his/her qubits in an appropriate basis and broadcasts through a public classical communication channel the measurement outcome based on which the receiver carries out necessary actions.By introducing an auxiliary particle and making selective measurement on it,the receiver can reconstruct the desired state with probability less than unity.The result shows that by using different type of generalized Bell states channel,the probability of joint remote preparation of an arbitrary three-qubit state is the same.While the generalized Bell states channel is maximally entangled,the joint remote preparation obtains the maximall total success probability.

Schemes for deterministic joint remote preparation of an arbitrary tripartite four-qubit entangled state

Peng-Cheng Ma, Gui-Bin Chen, Xiaowei Li +1 more

Abstract We present two schemes for the joint remote state preparation (JRSP) of an arbitrary tripartite four-qubit entangled state with complex coefficients via four and two three-qubit GHZ states as the quantum channel, respectively. In these schemes, the two senders share the original state which they wish to help the receiver remotely prepare. To complete the JRSP schemes, some novel sets of mutually orthogonal basis vectors are introduced. It is shown that, only if the two senders collaborate with each other, and perform projective measurements under a suitable measuring basis on their own qubits respectively, can the receiver reconstruct the original state by means of some appropriate unitary operations. We demonstrate, in our both schemes, the total success probability of the JRSP can reach 1. Moreover, compared with the first scheme in this paper, the advantage of the second scheme is that the entanglement resource can be reduced.

Deterministic joint remote preparation of arbitrary four-particle genuine entangled state

Jian Li, Jin-Rui Nie, Zhao Peijun +2 more

A novel deterministic joint remote preparation scheme of arbitrary four-particle genuine entangled state from one sender to either of two receivers is proposed. Two three-particle Green-Horne-Zeilinger (GHZ) states and one four-particle GHZ state are used as the quantum channel. The presented scheme is realized through orthogonal projective measurement of the Hadamard transferred basis and recovery operation U|ijk〉. Some useful and general measurement bases have been constructed. The classical communication cost of the presented scheme is also calculated. Our analysis confirms the feasibility and validity of the proposed method, and shows that it has a 100% probability of success in preparation of the target quantum state.

SCHEMES FOR REMOTELY PREPARING AN ARBITRARY FIVE-QUBIT BROWN-TYPE STATE

Song-Ya Ma, PING TANG, Ming‐Xing Luo

Two novel schemes via different entanglement resources are put forward to remotely preparing a five-qubit Brown-type state with high probabilities. To design the schemes, some useful measurement bases with the aid of Hurwitz matrix equation are constructed, which have no restrictions on the coefficients of the prepared state. Through a four-particle projective measurement and two-step three-particle projective measurement under the novel sets of mutually orthogonal basis vectors, the remote preparation can be realized with the probability 50% and 100% in general case, respectively. To improve the probability, the special ensembles of the prepared state that the success probability reaches up to 100% are discussed for the first scheme by the permutation group. Furthermore, the present schemes are extended to the nonmaximally entangled quantum channel.

Joint Remote State Preparation of a Four-Dimensional Quantum State

Peng Jia-yin, Ming-Qiang Bai, Zhiwen Mo

We present several protocols for joint remote state preparation of a single(two)-quadbit state with real (or complex) coefficients via a projective or positive operator-valued measure. In our schemes, three(five)-quadbit non-maximally entangled state(s) have been employed as the quantum channel and several appropriate mutually orthogonal basis are delicately constructed. Finally, the present schemes are extended to the (N + M) senders' case.
