Abstract

A tripartite continuous-variable entangled state was generated and its full inseparability was verified based on the variances of the relative positions and the total momentum. The violations of all the inequalities verified the presence of genuine tripartite entanglement. These violations ensured that a suitable truly tripartite quantum communication protocol using the generated state would succeed.
