A Scheme for Controlled Cyclic Asymmetric Remote State Preparation in Noisy Environment

Abstract

As research on quantum computers and quantum information transmission deepens, the multi-particle and multi-mode quantum information transmission has been attracting increasing attention. For scenarios where multi-parties transmit sequentially increasing qubits, we put forward a novel (N + 1)-party cyclic remote state preparation (RSP) protocol among an arbitrary number of players and a controller. Specifically, we employ a four-party scheme in the case of a cyclic asymmetric remote state preparation scheme and demonstrate the feasibility of the scheme on the IBM Quantum Experience platform. Furthermore, we present a general quantum channel expression under different circulation directions based on the n-party. In addition, considering the impact of the actual environment in the scheme, we discuss the feasibility of the scheme affected by different noises.

Controlled Cyclic and Bidirectional Hybrid Quantum Communication of Arbitrary Two‐Qubit States

“…What's more, in comparison with the bidirectional hybrid communication protocols, [18][19][20][21][22][23] quantum information is just transmitted between two parties, but our protocol can transmit information among multiple participants. Compared to other cyclic communication protocols, [24][25][26][27][28][29][30][31] our protocol can transmit information in two directions, in which the participants can send quantum states to each other. All in all, our scheme enables simultaneous bidirectional transmission of quantum states among multiple participants, it can greatly reduce the overall communication time, thus achieving faster and more efficient data transmission.…”

“…In the same year, a cyclic remote state preparation (CRSP) scheme [25] for circularly preparing three known single-qubit states with the control of one supervisor was also presented. Later, other types of CQT [26][27][28][29] and CRSP [30][31][32][33] schemes had been reported. But in these works, [24][25][26][27][28][29][30][31][32][33] two neighboring observers cannot exchange their states with each other, they only teleport states in one direction.…”

To break the limitation of cyclic communication in a single direction, the study of cyclic and bidirectional quantum communication is a must.…”

Controlled cyclic remote preparation

“…In addition to these mentioned protocols for cyclically preparing arbitrary single-qubit states, Sun et al [35] presented a protocol for cyclically preparing arbitrary two-qubit states and studied two-type quantum noises. Other protocols for cyclic remote preparation had been also proposed, such as multi-hop [36] and asymmetric [37] CRSP schemes.…”
