Abstract
The aim of our work is to realize the atomic storage of continuous variable quantum information encoded in light fields. Following recent ideas, we propose a new scheme based on both Raman absorption and gradient echo and compare its efficacy with electromagnetically induced transparency (EIT)-based memories. A tuneable source of low frequency squeezing at rubidium wavelengths was built to study and compare the efficacy of the memory schemes. We will present our latest theoretical investigations and experimental observations of the coupling of squeezing to Rubidium atoms using these protocols.
