An enhanced graph state distribution method for quantum networks

<jats:title>Abstract</jats:title>
<jats:p>Multi-particle entanglement state distribution is a crucial component for executing the quantum communication or computation protocols over quantum networks, and the graph state is an important class of multi-particle entanglement states. If the graph states can be efficiently distributed over quantum networks, the execution costs of the quantum communication or computation protocols will be greatly improved. Therefore, this study proposes an enhanced graph state transfer algorithm, which is used to distribute the graph state across a quantum network to reduce the required number of qubit measurements, quantum operation implementation, and qubit consumption without adding any additional quantum device.</jats:p>
