In this paper we propose a non-Markovian quantum channel approach to mitigating the
degradation of the average fidelity in continuous-variable quantum teleportation. The non …

In recent years, the development of graph states has opened a bright prospect for the
generation of multipartite entangled states. However, due to the influences of noises in the …

Based on ** et al.'s hierarchical remote preparation scheme of an arbitrary m-qudit state
with three agents, we propose one scheme for multiple agents by utilizing the symmetry of …

Fusing the idea of short-distance teleportation and remote quantum state preparation (QSP),
we first propose a novel deterministic QSP scheme to prepare an arbitrary two-particle state …

To meet the practical needs that the capabilities of agents in a quantum communication
network are often different, we propose two deterministic schemes to achieve hierarchical …

High‐dimensional quantum system exhibits unique advantages over the qubit system in
some quantum information processing tasks. A program is presented for implementing …

The weight graph states (WGS) usually serve as the imperfect generation of the graph states
due to the limitation in experiments. In this paper, we study the deterministic remote state …

In this article, we first present a new scheme that can simultaneously produce two perfect
replicas of arbitrary unknown single-qubit states in two different directions with the aid …

The purpose of this article is to further investigate the assisted cloning of an arbitrary
unknown state via maximal slice states under the control of the supervisor. By making use of …

Abstract Joint Remote State Preparation provides a useful way to securely transfer the
known quantum states to the distant nodes. However, the limitation of resources often leads …
