  We investigate coherent single surface-plasmon transport in a metal nanowire
strongly coupled to two colloidal quantum dots. Analytical expressions are
obtained for the transmission and reflection coefficients by solving the
corresponding eigenvalue equation. Remote entanglement of the wave functions of
the two quantum dots can be created if the inter-dot distance is equal to a
multiple half-wavelength of the surface plasmon. Furthermore, by applying
classical laser pulses to the quantum dots, the entangled states can be stored
in metastable states which are decoupled from the surface plasmons.
