We have developed a quantum memory that is completely compatible with current quantum information processing for continuous variables of light, where arbitrary frequency sidebands of a squeezed vacuum can be stored and retrieved using bichromatic electromagnetic induced transparency. The 2 MHz sidebands of squeezed vacuum pulses with temporal widths of 470 ns and a squeezing level of -1.78±0.02 dB were stored for 3 μs in laser-cooled 87Rb atoms. Squeezing of -0.44±0.02 dB, which is the highest squeezing reported for a retrieved pulse, was achieved.
