Abstract

In this paper, we propose a controlled remote state preparation scheme for a known eight-qubit entangled state. In this scheme, the sender, controller, and receiver share a six-qubit cluster state. The sender first performs a two-qubit state measurement, and the controller performs a corresponding two-qubit system measurement based on the sender’s measurement result. After receiving the measurement results from the sender and controller, the receiver can reconstruct this initial eight-qubit entangled state by using an appropriate unitary operation. This unitary operation depends on the different measurements of the sender and controller.
