We experimentally investigated propagation of squeezed vacuum pulses in a cold atomic ensemble with electromagnetically induced transparency. 930 ns of the squeezed vacuum pulse was incident on the laser cooled 87Rb atoms and its propagation was analyzed using time domain method. Bandwidth of the squeezing was dramatically reduced due to the EIT and the slow propagation was clearly observed for the pulsed squeezed vacuum.

The squeezed vacuum resonant on the (87)Rb D1 line (probe light) was injected into an optically dense rubidium gas cell with a coherent light (control light). The output probe light maintained its quadrature squeezing within the transparency window caused by the electromagnetically induced transparency (EIT). The results reported here are the first realization of EIT in the full quantum regime.
