“…The sender and receiver in RSP share an entangled state, the sender knows the classical information of the target state but does not possess the physical particle. The sender only needs to do projective measurements or POVM measurements with the classical information coded in, which saves the resources of preparing the target state in teleportation [12,13].…”

Joint remote state preparation （JRSP for short）can increase the security of quantum communication by distributing different parts of classical information to different senders. However, the communication efﬁciency in terms of ﬁdelity decreases with the increase of intermediate nodes in multi-hop network. In this paper, we try to explore methods to improve ﬁdelity of JRSP in multi-hop network presented by Zhang and Chen in 2023 Phys. Scr. 98 065107. Speciﬁcally, correlated Pauli noise with partial memory was introduced into the the shared channel. We ﬁnd that the ﬁdelity increases with the increase of memory parameters, which compensates for the loss of ﬁdelity caused by the increase of network nodes.

“…Subsequently, the dishonest participant P 1 cannot get any idea about the marked state |m⟩ from his operations, even though D announces S 9 . So, P 1 can acquire D's secret shares with probability 9 32 . However, as previously mention, if P 1 resend two qubits of the triplet state to the participants P 2 and P 3 then D can detect such deception with probability 25 32 .…”

SummaryThis study presents a quantum secret sharing (QSS) protocol designed using Grover's search algorithm in a noisy environment. The proposed protocol utilizes Grover's three‐particle quantum state. The proposed scheme is divided into secret information sharing and eavesdropping checking. The dealer prepares an encoded state by encoding the classical information as a marked state and shares the states' qubits between three participants. Using the amplitude‐damping noise and the phase‐damping noise as conventional noisy channels, it can be demonstrated that secret information can be conveyed between participants with some information lost. The security analysis shows the scheme is stringent against malicious participants or eavesdroppers. The simulation analysis is done on the cloud platform IBM‐QE thereby showing the practical feasibility of the scheme. Finally, an application of the proposed scheme is demonstrated in visual cryptography using the GNEQR representation of images.

This study focuses on the impact of amplitude-damping noise, which diminishes the fidelity of the teleported quantum state on an existing cyclic quantum teleportation scheme [V. Verma, D. Yadav and D. K. Mishra, Opt. Quantum Electron. 53 (2021) 1]. The CQT scheme involves three participants performing a cyclic teleportation along with a controller to supervise the protocol. We also propose weak measurement and reversal measurement operations as potential solutions to combat the noise-induced decoherence and improve the fidelity of the existing CQT scheme. The simulation results showcase the improvements achieved in the fidelity calculation when implementing the potential solutions. The findings hold immense potential for quantum information communications in practical situations.
