Abstract

We propose a protocol transferring an arbitrary unknown two-qubit state using the quantum channel of a four-qubit genuine entangled state. Simplifying the four-qubit joint measurement to the combination of Bell-state measurements, it can be realized more easily with currently available technologies.

Assisted cloning of an arbitrary unknown two-qubit state via a genuine four-qubit entangled state and positive operator-valued measure

Lian Fang Han, Hao Yuan, Yang Ming +1 more

A protocol for cloning an arbitrary unknown two-qubit state and its orthogonal complement state with the assistance of a state preparer is presented. In this paper, a genuine four-particle entangled state which cannot be reduced to the product of two Bell states is used as the quantum channel. Moreover, positive operator-valued measure (POVM) instead of usual projective measurement is employed. In one hand, the usual teleportation is required. And in another hand, the perfect copies and complement copies of an unknown two-particle state can be implemented with a certain probability in the help of the state preparer.

Teleportation for an Unknown Entangled State Without Any Joint Measurement via Josephson Charge Qubits

Da-Chuang Li, Zheng Xiao-Hu, Dong Ping +1 more

An experimentally feasible scheme for teleportation of an arbitrary unknown entangled state is proposed. Our scheme is based on Josephson charge qubits, where we do not need any joint measurement. Moreover the successful probability and fidelity of the teleportation can both reach 1.0. The current scheme can be realized within the current experimental technology.

General form of genuine multipartite entanglement quantum channels for teleportation

Ping-Xing Chen, Shi-Yao Zhu, Guang‐Can Guo

Recently Yeo and Chua [Phys. Rev. Lett. 96, 060502 (2006)] presented an explicit protocol for faithfully teleporting an arbitrary two-qubit state via a genuine four-qubit entanglement channel. Here we generalize completely their results to teleporting an arbitrary $N$-qubit state via genuine $N$-qubit entanglement channels. And we present the general form of the genuine multipartite entanglement channels, namely, the sufficient and necessary condition the genuine $N$-qubit entanglement channels must satisfy to teleport an arbitrary $N$-qubit state.

Quantum teleportation of a two-qubit arbitrary entangled state with four-qubit cluster state

Hao Yuan, Min Kong, Guo‐Zhu Pan +1 more

Abstract Based on the four-qubit cluster state as quantum channel, we put forward a novel scheme for teleporting a two-qubit arbitrary entangled state. The necessary quantum operations for accomplishing the task are two controlled-not gate operations, one controlled-phase gate operation, four single-qubit measurements and two single-qubit transformed operations. They are easily achievable with current experimental techniques. Besides, the present scheme is deterministic because its probability of success is 100 % .

Teleportation of an Unknown Atomic Entangled State Without Any Joint Bell-state Measurement via a Cluster State

Zhuo‐Liang Cao, Da-Chuang Li

An experimentally feasible scheme for teleportation of an unknown two-atom entangled state is proposed. Our scheme uses a cluster state as the quantum channel, where we do not need any joint Bell-state measurement. Moreover the successful probability and fidelity of teleportation can both reach 1.0. The current scheme can be realized within the current experimental technology.

Quantum Controlled Teleportation of Arbitrary Two-Qubit State via Entangled States

Lei Shi, Kaihang Zhou, Jiahua Wei +2 more

We put forward an efficient quantum controlled teleportation scheme, in which arbitrary two-qubit state is transmitted from the sender to the remote receiver via two entangled states under the control of the supervisor. In this paper, we use the combination of one two-qubit entangled state and one three-qubit entangled state as quantum channel for achieving the transmission of unknown quantum states. We present the concrete implementation processes of this scheme. Furthermore, we calculate the successful probability and the amount of classical information of our protocol.
