  We report on quantum, classical, and total correlations in a set of distant
quantum emitters coupled via their interaction with the plasmon modes of a
one-dimensional waveguide driven by an external laser field. The coupling of
the emitters with the plasmonic modes and its influence on the collective decay
rate suggest that entanglement does not play a significant role in the qubit
dynamics. Rather, discord is the quantity that matters and should be harnessed
as a resource.
