In this paper we consider the problem of the bidirectional state transfer of a 2-qubit and a 3-qubit quantum state unknown to the parties, respectively, who intend to send the respective states in the site of the other party. These states are intended for transfer but are not possessed by the intender. The protocol has a Mentor whose role is in the fabrication of entangled channels, distribution of qubits through the noisy environment in order to create entanglement sharing and finally fixing one of the several courses of the protocol. The role of the Mentor is thereby completed. The protocol is overseen by a controller whose action signals the final steps to be taken in the protocol. Three types of noises are considered through three different Kraus operators. There is an analysis of the fidelity of the protocol corresponding to three types of noises.

“…These types of quantum communication schemes are known as quantum remote state preparation (RSP) protocols which were first introduced by Pati [34]. Following the work of Pati [34], several researchers developed various modified forms of quantum remote state preparation schemes such as controlled RSP [35][36][37], joint remote state preparation [38][39][40], cyclic RSP [41][42][43], bi-directional RSP [44][45][46], conference RSP [47], etc. However, in the process of quantum state transfer or creation of states in remote locations there will inevitably be interactions with the environment.…”

In this paper we discuss a quantum multi-tasking protocol for preparation of known one-qubit and two-qubit states respectively in two different locations. The ideal remote state preparation protocol is discussed in the first place in which a five-qubit entangled state is utilized. The design for the preparation of such entanglement is also presented and run on IBM quantum composer platform. The effects of three types of noises on the protocol are discussed and in all these cases the reduced fidelities of the process are calculated. The variations of these fidelities with respect to different parameters are analysed.

“…In the past few years, Mentor initialed multiparty quantum communication has been studied by some groups. The basic idea of a Mentor initialed JRSP protocol is to joint remote preparation of an arbitrary quantum state via quantum channel constructed by the Mentor [69][70][71][72]. It is different to another important branch of JRSP, controlled JRSP, whose task is joint remote preparation of the original quantum state under the controller's control via quantum channel shared in advance [73][74][75][76].…”

“…It is different to another important branch of JRSP, controlled JRSP, whose task is joint remote preparation of the original quantum state under the controller's control via quantum channel shared in advance [73][74][75][76]. In 2022, Mandal et al proposed a scheme for controlled remote preparation of the original single-qubit states initialed by a Mentor [69]. Choudhury and Samanta proposed the protocol for Mentor initialed joint remote preparation of the original single-qubit state by using three two-qubit Bell states as the quantum channel [70].…”

“…In [69], the sender can perform single-qubit projective measurement according to the information of prepared single-qubit state a 0 |0〉 + a 1 |1〉 with real coefficients a 0 , a 1 to avoid the requirement that the sender should construct the multiparticle POVM measurement according to his knowledge of the original state. But when the prepared state becomes an arbitrary n-qudit state with arbitrary complex coefficients, the scheme in [69] does not work. Different to Refs.…”

We propose a protocol to Mentor initiated hierarchical joint remote prepare the arbitrary n-qudit state with generalized Bell states.The agents share generalized Bell states with the Mentor. The Mentor performs five-qudit projective measurements on his entangled particles to initiate the quantum channel shared by the agents. All the senders share the information of the prepared state and make quantum measurements on their particles based on the state to be prepared. The agent in the upper grade needs only the assistance of one of the agents in the lower grade to reconstruct the original state, while the agents in the lower grade need the assistance of all the other agents to recover the original state. It is more convenient in application than others since the agents in the protocol only requires two-particle entanglement for Mentor initiated hierarchical joint remote preparation of an arbitrary n-qudit state.
