• Abstract: In this paper, we reinvestigate remote state preparation by using the prepared non-maximally entangled channel. An innovative remote state preparation protocol is developed for deterministically preparing information encoded in quantum states without additional consumption of quantum resources. We have increased the success probability of preparing a d-dimensional quantum state to 1 via a non-maximally entangled quantum channel. A feasibly experimental scheme is also designed to realize the above-mentioned deterministic scheme. This work provides a valuable method to address decoherence and environmental noises in the practicalization of quantum communication tasks.

  In this paper, we analyze the feasibility and efficiency of extracting high-order moments from noisy states. We first show that there exists a quantum protocol capable of accomplishing this task if and only if the underlying noise channel is invertible. Our work contributes to a deeper understanding of how quantum noise could affect high-order information extraction and provides guidance on how to tackle it.

  We have designed a novel deterministic joint remote state preparation scheme using a degenerated non-maximally entangled state directly. A protocol for deterministic joint remote preparation of a two-dimensional quantum state via a non-maximally hyperentangled quantum channel has been devised. No matter how weak the shared entanglement is, the success probability of communication is maintained at 100% as soon as it exists.
