Abstract

Abstract In this paper, we propose two schemes for asymmetric bidirectional controlled remote state preparation (BCRSP) via seven-qubit and ten-qubit entangled states as the quantum channel and in real and complex Hilbert space, respectively. In these schemes, two distant parties, Alice and Bob, are not only senders but also receivers, and Alice wants to remotely prepare a single-qubit state at Bob’s site; at the same time, Bob wishes to help Alice remotely prepare a tripartite three-qubit W-type state. It is shown that only if the two senders and the controller collaborate with each other, the asymmetric BCRSP can be completed successfully.

Asymmetric and deterministic bidirectional remote state preparation under the supervision of a third party

Abstract We present two schemes for asymmetric controlled bidirectional remote state preparation (CBRSP) with real and complex coefficients via seven- and ten-qubit entangled states, respectively, as the quantum channel. In these schemes, two distant parties—Alice and Bob—are not only senders but also receivers: Alice wants to remotely prepare a single-qubit state at Bob’s site; at the same time, Bob wishes to help Alice remotely prepare a two-qubit state. It is shown that the asymmetric CBRSP be can be completed successfully only if the two senders and the controller collaborate with each other. We demonstrate that, in our schemes, the total success probability of the asymmetric CBRSP can reach 1, that is, the schemes are deterministic.

Bidirectional controlled remote state preparation in three-dimensional system

Yuan Bai, Peng-Cheng Ma, Gui-Bin Chen +2 more

We present a novel scheme for bidirectional controlled remote state preparation (BCRSP) in a three-dimensional system with a six-qutrit entangled state as the quantum channel. In this scheme, two distant parties, Alice and Bob, are not only senders but also receivers. Alice wants to remotely prepare a single-qutrit equatorial state at Bob’s site, while at the same time, Bob wishes to help Alice by remotely preparing another single-qutrit equatorial state. It is shown that, only if the two senders and the controller collaborate with each other, the BCRSP can be completed successfully.

Scheme for Asymmetric and Deterministic Controlled Bidirectional Joint Remote State Preparation*

Jin 锦 Shi 施, You-Bang Zhan

Abstract The scheme for asymmetric and deterministic controlled bidirectional joint remote state preparation by using one ten-qubit entangled state as the quantum channel is proposed. In this scheme, Alice and David want to remotely prepare an arbitrary single-qubit state at Bob’s site, at the same time, Bob and Eve wish to help Alice remotely prepare an arbitrary two-qubit entangled state. Alice and Bob can simultaneously prepare the desired states with the cooperation of David and Eve under the control of Charlie .

An asymmetric controlled bidirectional remote preparation protocol of three- and four-qubit equatorial states

Minrui Wang, Zheng Xiang, Peng Ren

A scheme for asymmetric controlled bidirectional remote state preparation by utilizing 15-qubit entangled state as quantum channel is proposed. In this paper, we present a new protocol that Alice prepares a three-qubit equatorial state for Bob and Bob prepares a four-qubit equatorial state for Alice at the same time under Charlie’s control. The success of this scheme cannot be separated from the controller Charlie. In addition, we give some analysis and conclusions by comparing with other schemes. The auxiliary qubits and operations are not required in our scheme. In particular, the success probability of the receivers restoring the prepared states can reach 100%. Thus, our scheme has better performance.

Asymmetric controlled bidirectional remote preparation of two- and three-qubit equatorial state

Yiru Sun, Xiu‐Bo Chen, Gang Xu +2 more

In this paper, a novel asymmetric controlled bidirectional remote preparation scheme is proposed. In our scheme, Alice and Bob are not only the senders but also the receivers with the control of Charlie. By using the eleven-qubit entangled state as the quantum channel, Alice prepares an arbitrary two-qubit equatorial state for Bob and Bob prepares an arbitrary three-qubit equatorial state for Alice simultaneously. Firstly, we give the construction process of the quantum channel. Secondly, the whole recovery operations are given. Alice and Bob can recover the prepared state determinately. Thirdly, we consider the effect of the noisy environment (amplitude-damping and phase-damping) in our scheme and calculate the fidelities of the output states. Finally, since our scheme does not need additional operations and auxiliary qubits, the efficiency of our scheme is higher than that of the previous schemes.

Hybrid bidirectional controlled quantum communication of a tripartite three-qubit entangled state

Qun-Yong Zhang, P F Ma, You-Bang Zhan

Abstract We present a novel scheme for hybrid bidirectional controlled quantum communication (HBCQC) using a nine-qubit entangled state as the quantum channel. In this scheme, the two remote parties, Alice and Bob, act as both senders and receivers. Alice seeks to teleport an unknown single-qubit state to Bob; simultaneously, Bob intends to assist Alice in remotely preparing an arbitrary tripartite three-qubit entangled state. It is shown that the HBCQC can be completed successfully only if the two senders and the controller collaborate with one another. This scheme is well-suited for heterogeneous and uncoordinated quantum networks, and it advances both their practical implementation and theoretical foundations.
