Deterministic Controlled Remote State Preparation of Arbitrary Real-parameter Multi-qubit States via Three-qubit Entangled States

Abstract

This paper offers a theoretical protocol for deterministic controlled remote state preparation of arbitrary real-parameter multi-qubit states, in which the maximally three-qubit entangled states are used as quantum channel. We elaborate the processes of implementing remote state preparation of the real-parameter two- and three-qubit states, and extend the protocol to realize the real-parameter n-qubit states. By performing the appropriate multi-qubit projective measurement basis and multi-qubit unitary operations, the successful probability of our scheme can reach 100%.
