A scheme to generate shared tripartite entangled states, with two-trappedatoms in a cavity held by Alice (qubits A1 and A2) entangled to a singletrapped atom in a remote lab owned by Bob (B), is proposed. The entanglement isgenerated through interaction of trapped atoms with two mode squeezed lightshared by the two cavities. The proposed scheme is an extension of the proposalof ref. [W. Son, M. S. Kim, J. Lee, and D. Ahn, J. Mod. Opt. 49, 1739 (2002)],where the possibility of entangling two remote qubits using a bipartitecontinuous variable state was examined. While the global negativity detects thefree entanglement of the three atom mixed state, the bound entanglement isdetected by the negativity calculated from pure state decomposition of thestate operator. The partial negativities calculated by selective partialtransposition of the three atom mixed state detect the pairwise entanglement ofqubit pairs A1B, A2B, and A1A2. The entanglement of three atoms is found to beW-like, no GHZ like quantum correlations being generated.
