“…Multi-hop network is an important construction of quantum repeater [42,43]. Quantum teleportation in multi-hop network has attracted much attention [44][45][46][47][48][49][50][51][52][53][54]. Recently, Zhang and Chen proposed a JRSP scheme in multi-hop network and considered its performance under noise channel [55].…”

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.
