“…The idea of RSP has been generalized, recently, in many other ways. For example, RSP schemes are proposed for remote preparation of equatorial states of an n-level quantum system [11], four-qubit GHZ state [36], multi-qubit GHZ state [37], four-qubit cluster-type state [38,39], arbitrary two-qubit state [40] and W state [11,41,42]. Further, several schemes for JRSP have been constructed.…”

“…Using measurement outcomes of the senders, the receiver can apply appropriate unitary operations and reconstruct the unknown quantum state, which is jointly transmitted by the senders. Extending this idea, JRSP schemes have been proposed for, among others, two-qubit equatorial states [27], W and W-type states [41,42], arbitrary two-qubit state [40], four-qubit cluster-like state [24], five-qubit Brown state [30], multi-qubit states [31] and arbitrary two and three-qubit entangled states [32]. Further generalizing these ideas, schemes were proposed for controlled RSP [44], controlled JRSP [45], JRSP between multi-receiver and multi-sender [28], multi-party JRSP of an arbitrary mqubit state [29], multi-party controlled JRSP [26], deterministic JRSP [46] and JRSP with a passive receiver [25].…”

It is shown that a realistic controlled bidirectional remote state preparation is possible using a large class of entangled quantum states having a particular structure. Existing protocols of probabilistic, deterministic and joint remote state preparation are generalized to obtain the corresponding protocols of controlled bidirectional remote state preparation (CBRSP). A general way of incorporating the effects of two wellknown noise processes, the amplitude-damping and phase-damping noise, on the probabilistic CBRSP process is studied in detail by considering that noise only affects the travel qubits of the quantum channel used for the probabilistic CBRSP process. Also indicated is how to account for the effect of these noise channels on deterministic and joint remote state CBRSP protocols.

“…3) we need more than one sender for the secrecy of the initial message/state to be transmitted in a hierarchical manner. This paper aims to address this particular issue and design a new type of scheme for hierarchical quantum communication, which we would refer to as hierarchical joint remote state preparation (HJRSP) scheme in analogy with the well known joint remote state preparation (JRSP) schemes [17,18,19,20].Here, it would be apt to note that there exists a variant of teleportation known as RSP, where a known quantum state is remotely prepared at the receiver's end. Thus, RSP may be viewed as teleportation of a known quantum state.…”

“…Subsequently, a large amount of work has been carried out on RSP. In these works RSP has been implemented in probabilistic, deterministic, controlled and controlled bidirectional manner using different quantum states, such as n-level, 4-qubit GHZ state, multi-qubit GHZ state, 4qubit cluster-type state, arbitrary two qubit state, and W state [17,18,19,20,22,23,24,25,26,27]. Interestingly, a few experimental realizations of some of the RSP schemes have also been reported in the past [28,29,30,31,32,33].In 2008, the RSP scheme was modified to a three-party scheme of the joint RSP (JRSP) [17].…”

A novel scheme for quantum communication having substantial applications in practical life is designed and analyzed. Specifically, we have proposed a hierarchical counterpart of the joint remote state preparation (JRSP) protocol, where two senders can jointly and remotely prepare a quantum state. One sender has the information regarding amplitude, while the other one has the phase information of a quantum state to be jointly prepared at the receiver's port. However, there exists a hierarchy among the receivers, as far as powers to reconstruct the quantum state is concerned. A 5-qubit cluster state has been used here to perform the task. Further, it is established that the proposed scheme for hierarchical JRSP (HJRSP) is of enormous practical importance in critical situations involving defense and other sectors, where it is essential to ensure that an important decision/order that can severely affect a society or an organization is not taken by a single person, and once the order is issued all the receivers don't possess an equal right to implement it. Further, the effect of different noise models (e.g., amplitude damping (AD), phase damping (PD), collective noise and Pauli noise models) on the HJRSP protocol proposed here is investigated. It is found that in AD and PD noise models a higher power agent can reconstruct the quantum state to be remotely prepared with higher fidelity than that done by the lower power agent(s). In contrast, the opposite may happen in the presence of collective noise models. We have also proposed a scheme for probabilistic HJRSP using a non-maximally entangled 5-qubit cluster state.have been proposed. For example, schemes were proposed for quantum information splitting (QIS) or controlled teleportation (CT) [8,9], quantum secret sharing (QSS) [10], hierarchical quantum information splitting (HQIS) [11,12], remote state preparation (RSP) [13], etc. (see Ref.[6] for a review). All these schemes can be viewed as variants of teleportation.Recently, a few hierarchical versions of already existing aspects of quantum communication (variants of teleportation) have been proposed. Specifically, hierarchical quantum information splitting (HQIS) [11,12,14,15], hierarchical quantum secret sharing (HQSS) [12], hierarchical dynamic quantum secret sharing (HDQSS) [16], etc., have been proposed in the recent past. It is also shown that these schemes have enormous practical importance (for a detailed discussion on the interesting applications of these schemes see Sec. 1 of Refs. [12,16]). In these protocols, there is a hierarchy among the powers of receivers (agents) to reconstruct a quantum state sent by the sender, i.e., the agents are graded in accordance to their power for the reconstruction of an unknown quantum state. Specifically, in HQIS the receivers can reconstruct the teleported quantum state with the help of other receivers (as in QIS [8,9]), where the power of a particular receiver is decided by the minimum number of receivers required to cooperate with him to enable him to reconstruct the s...
