  In this paper, we have reinvestigated probabilistic quantum communication
protocols and developed a nontraditional remote state preparation protocol that
allows for deterministically transferring information encoded in quantum states
using a non-maximally entangled channel. With an auxiliary particle and a
simple measurement method, the success probability of preparing a d-dimensional
quantum state is increased to 1 without spending additional quantum resources
in advance to improve quantum channels, such as entanglement purification.
Furthermore, we have designed a feasible experimental scheme to demonstrate the
deterministic paradigm of transporting a polarization-encoded photon from one
location to another using a generalized entangled state. This approach provides
a practical method to address decoherence and environmental noises in actual
quantum communication.
