Abstract

In this paper, we propose a novel scheme for deterministic hierarchical joint remote state preparation (HJRSP). Two senders and three receivers are involved. One sender has the amplitude information of the target state to be prepared at the receiver's port, while the other one has the phase information. There is a hierarchy among the receivers concerning their powers to reconstruct the target state. 6-particle partially entangled state is used as the quantum channel. Participants perform projective measurements under elaborate measurement bases. According to their measurement results, the receiver reconstructs the target state by means of appropriate unitary operation. The higher-power receiver reconstructs the target state independently, and the lower-power receiver reconstructs the target state if and only if all the other receivers help him (her). Different from the previous HJRSP scheme utilizing partially entangled channels, auxiliary qubit is not required in our scheme, and unit success probability can be achieved. It is shown that the success probability is independent of the parameters of the partially entangled quantum channel.

Deterministic hierarchical joint remote state preparation with six-particle partially entangled state

Na Chen, Bin Yan, Geng Chen +2 more

In this paper, we present a novel scheme for hierarchical joint remote state preparation (HJRSP) in a deterministic manner, where two senders can jointly and remotely prepare an arbitrary single-qubit at three receivers’ port. A six-particle partially entangled state is pre-shared as the quantum channel. There is a hierarchy among the receivers concerning their powers to reconstruct the target state. Due to various unitary operations and projective measurements, the unit success probability can always be achieved irrespective of the parameters of the pre-shared partially entangled state.

Deterministic joint remote state preparation via partially entangled quantum channel

Na Chen, Dongxiao Quan, Changhua Zhu +2 more

In this paper, we propose a scheme for deterministic joint remote state preparation (JRSP). Two spatially separated senders intend to help a receiver remotely prepare an arbitrary single-qubit state. Four-particle partially entangled state is constructed to serve as the quantum channel. By determining right unitary operations for the senders and appropriate recovery operations for the receiver, the target state can be reestablished with unit success probability, irrespective of the channel parameter.

Deterministic joint remote state preparation of arbitrary single- and two-qubit states

Na Chen, Dongxiao Quan, Fufang Xu +2 more

In this paper, two novel schemes for deterministic joint remote state preparation (JRSP) of arbitrary single- and two-qubit states are proposed. A set of ingenious four-particle partially entangled states are constructed to serve as the quantum channels. In our schemes, two senders and one receiver are involved. Participants collaborate with each other and perform projective measurements on their own particles under an elaborate measurement basis. Based on their measurement results, the receiver can reestablish the target state by means of appropriate local unitary operations deterministically. Unit success probability can be achieved independent of the channel's entanglement degree.

Probabilistic controlled remote state preparation of an arbitrary two-qubit state via partially entangled states with multi parties

Jiahua Wei, Lei Shi, Zhiyan Xu +4 more

We propose a novel and efficient scheme for probabilistic controlled remote state preparation of an arbitrary two-qubit quantum state with the aid of the introduction of auxiliary particles and some appropriate local unitary operations. In this scheme, two partially three-qubit entangled states are used as quantum channel. The controlled preparation with one sender, two receivers and one controller can be realized when the information of nonmaximally entangled states are only available for the sender. Furthermore, the concrete implementation processes of this proposal are presented, and the successful probability of our scheme are calculated in the general case and special case, respectively.

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.
