Abstract: A general approach to investigate the hierarchical remote state preparation (HRSP) is presented, and the possibility of realizing HRSP is systematically proven using 4-qubit [Ω] state and 4-qubit cluster state as quantum channels, respectively. Subsequently, the proposed HRSP scheme is generalized to a new aspect to study the hierarchical joint remote state preparation (HJRSP), and the HJRSP is possible using 5-qubit cluster state as the quantum channel. Further, the HJRSP scheme is modified into a probabilistic HJRSP scheme, and latter possibility is confirmed by using 5-qubit non-maximally entangled cluster state as the quantum channel.
