Controlled Remote State Preparation via General Pure Three-Qubit State

TL;DR

This paper introduces a novel protocol for controlled remote state preparation using general pure three-qubit states, expanding beyond GHZ states, with success probabilities that can reach unity in certain cases.

Contribution

It is the first to utilize general pure three-qubit states for remote state preparation, providing a broader class of quantum channels than previously used GHZ states.

Findings

Successful preparation probability can reach 1 in special cases.

General pure three-qubit states are effective for remote state preparation.

The protocol extends the range of quantum states used in remote preparation.

Abstract

The protocols for controlled remote state preparation of a single qubit and a general two-qubit state are presented in this paper. The general pure three-qubit states are chosen as shared quantum channel, which are not LOCC equivalent to the mostly used GHZ-state. It is the first time to introduce general pure three-qubit states to complete remote state preparation. The probability of successful preparation is presented. Moreover, in some special cases, the successful probability could reach unit.
