Query: Geometric Measure of Pairwise Quantum Discord for Superpositions of
  Multipartite Generalized Coherent States   We give the explicit expressions of the pairwise quantum correlations present
in superpositions of multipartite coherent states. A special attention is
devoted to the evaluation of the geometric quantum discord. The dynamics of
quantum correlations under a dephasing channel is analyzed. A comparison of
geometric measure of quantum discord with that of concurrence shows that
quantum discord in multipartite coherent states is more resilient to
dissipative environments than is quantum entanglement. To illustrate our
results, we consider some special superpositions of Weyl-Heisenberg, SU(2) and
SU(1,1) coherent states which interpolate between Werner and
Greenberger-Horne-Zeilinger states.
