“…The multiparty remote state preparation [24] or the joint remote state preparation (JRSP for short) was proposed [25]. JRSP schemes were designed to be deterministic [26][27][28][29] or in probability [30][31][32][33][34] due to different shared channel and different preparation process. JRSP of various states have been investigated, such as…”

Joint remote state preparation is an important method to transmit quantum information with more senders and higher security. In this paper, we present a deterministic joint remote state preparation scheme in multi-hop network with two senders and $N$ intermediate parties, using only projective measurements and recovery operations. We describe the scheme under the framework of density matrix to investigate the performance of the scheme in noisy environment. The relation of fidelity, noise rate and the number of intermediate nodes is given for three types of noise. It is revealed that the average fidelity attains its minimum when the noise rate is at the most uncertain point, decreases monotonically as the number of intermediate nodes increases. However, in some special cases, the average fidelity of the multi-hop scheme is greater than some existing one step joint remote state preparation scheme.

“…To overcome this shortcoming, researchers proposed joint remote state preparation (JRSP for short) [14] or multiparty remote state preparation [15]. The successful probability of JRSP would be equal to [16][17][18][19][20] or less than one hundred percent [21][22][23][24], which is determined by the target state and shared channel. The joint preparation of various states was investigated by researchers, such as mixed states [25], equatorial states [21,26,27], single-, two-, and three-qubit states [28][29][30][31] and fourdimensional states [32].…”

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.

“…Therefore, RSP schemes consume less qubit resources. So far, RSP has gained extensive interest and research, such as deterministic RSP (DRSP), [12,13] joint RSP (JRSP), [14][15][16][17][18] controlled RSP (CRSP), [19][20][21][22][23][24][25] and continuous variable RSP. [26,27] Several RSP programs have been experimentally implemented in linear optical systems, [28] cavity QED, [29][30][31] and nuclear magnetic resonance systems.…”

Deterministic remote preparation of multi-qubit equatorial states through dissipative channels

We investigate the influence of noisy environment on the remote preparation of the multi-qubit equatorial state, and specifically deduce the final states and fidelities of the remote preparation of the three-qubit and four-qubit equatorial states under diverse types of noisy environment, namely amplitude damping, bit flip, phase damping, phase flip, bit-phase flip, depolarization and non-Markov environments. The results show that when the decoherence factors of the front six noise are equal, the influence degrees of phase damped noise, bit flip noise, phase flip noise and bit-phase flip noise are similar, while the information loss caused by amplitude damped noise and depolarizing noise is less. In particular, the bit flip noise and depolarizing noise may have more complex effects on the remote state preparation (RSP) schemes depending on the phase information of target states, even the ideal cases that the fidelity values are always 1 for specific phase relations. In the non-Markov environment, owing to the back and forth of information between the environment and systems, fidelities exhibit oscillating behavior and the minimum value may stay greater than zero for a long evolutionary time. These results are expected to have potential applications for understanding and avoiding the influence of noise on remote quantum communication and quantum networks.
