Query: Non-separated states from squeezed dark-state polaritons in
  electromagnetically-induced-transparency media   Within the frame of quantized dark-state polaritons in
electromagnetically-induced-transparency media, noise fluctuations in the
quadrature components are studied. Squeezed state transfer, quantum
correlation, and noise entanglement between probe field and atomic polarization
are demonstrated in single- and double-$\Lambda$ configurations, respectively.
Even though a larger degree of squeezing parameter in the continuous variable
helps to establish stronger quantum correlations, inseparability criterion is
satisfied only within a finite range of squeezing parameter. The results
obtained in the present study may be useful for guiding experimental
realization of quantum memory devices for possible applications in quantum
information and computation.
