Query: Fundamental trade-off between the speed of light and photon current
  fluctuations in electromagnetically induced slow-light medium   Electromagnetically induced slow-light medium is a promising system for
quantum memory devices, but controlling its noise level remains a major
challenge to overcome. This work provides a new fundamental trade-off
relationship between the group velocity of light and photon current
fluctuations in such media, modeled as coherently controlled three-level
$\Lambda$-system interacting with bosonic bath. Considering the steady state
limits of a newly derived Lindblad-type equation, we find that the Fano factor
of the photon current maximizes to 3 at the minimal group velocity of light,
which holds true universally regardless of detailed values of parameters
characterizing the medium.
