    "abstract": "We have succeeded in observing ultraslow propagation of squeezed vacuum\npulses with electromagnetically induced transparency. Squeezed vacuum pulses\n(probe lights) were incident on a laser cooled 87Rb gas together with an\nintense coherent light (control light). A homodyne method sensitive to the\nvacuum state was employed for detecting the probe pulse passing through the\ngas. A delay of 3.1us was observed for the probe pulse having a temporal width\nof 10 us.",
