  • The dynamics of tripartite entanglement and intramolecular energy for one harmonic-and two anharmonic-vibrational modes in a symmetric trimer molecule is studied for various ini-tial states, where the entanglement is quantified in terms of concurrence and the interacting energy among three modes is calculated to establish a link between entanglement and en-ergy. It is shown that the concurrence and the interacting energy behave dominantly positive correlation for the localized state in the anharmonic-vibrational mode, while they are domi-nantly anti-correlated for the localized state in the harmonic-vibrational mode. The relation between bipartite entanglement and the energy in a subsystem is discussed as well. Those are useful for quantum computing and quantum information in high dimensional states prepared in polyatomic molecules.

Dynamics of Tripartite Entanglement and Intramolecular Energy in Symmetric Trimer Molecule

doi: 10.1063/1674-0068/29/cjcp1507148

Abstract: The dynamics of tripartite entanglement and intramolecular energy for one harmonic-and two anharmonic-vibrational modes in a symmetric trimer molecule is studied for various ini-tial states, where the entanglement is quantified in terms of concurrence and the interacting energy among three modes is calculated to establish a link between entanglement and en-ergy. It is shown that the concurrence and the interacting energy behave dominantly positive correlation for the localized state in the anharmonic-vibrational mode, while they are domi-nantly anti-correlated for the localized state in the harmonic-vibrational mode. The relation between bipartite entanglement and the energy in a subsystem is discussed as well. Those are useful for quantum computing and quantum information in high dimensional states prepared in polyatomic molecules.
