Abstract
A continuous-variable tripartite entangled state is experimentally generated by combining three independent squeezed vacuum states, and the variances of its relative positions and total momentum are measured. We show that the measured values violate the separability criteria based on the sum of these quantities and prove the full inseparability of the generated state.Year: 2003 PMID： 14525227 DOI： 10.1103/PhysRevLett.91.080404
