  The fluctuation conductivity of a moderately clean type II superconductor
with strong Pauli paramagnetic pair-breaking (PPB) is studied by focusing on
the quantum regime at low temperatures and in high magnetic fields. First, it
is pointed out that, as the PPB effect becomes stronger, the quantum
superconducting fluctuation is generally enhanced so that the Aslamasov-Larkin
(AL) fluctuation conductivity tends to vanish upon cooling. Further, by
examining other (the DOS and the Maki-Thompson (MT)) terms of the fluctuation
conductivity, the field dependence of the resulting total conductivity is found
to depend significantly on the type of the vortex lattice (or, glass) ordered
state at low temperatures where the strong PPB plays important roles. By
comparing the present theoretical results with the fluctuation-induced negative
magnetoresistance behavior upon entering a PPB-induced novel SC phase of Iron
selenide (FeSe), it is argued that the vortex matter states of the
superconducting order parameter in the second lowest ($n=1$) Landau level are
realized in FeSe in the parallel field configuration in high fields and at low
temperatures
