“…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.
