标题： Quantum memory in warm rubidium vapor with buffer gas

摘要： 使用温暖原子蒸气细胞实现量子存储具有吸引力，因为它们具有商业可用性，并且被认为可以减少实验复杂性。 尽管文献中报道的结果存在歧义，但我们证明可以在单个带有缓冲气体的细胞中实现量子存储，其中写入和读取光束几乎同向传播。 对于延迟时间长达4微秒的情况，发射的斯托克斯光子和反斯托克斯光子表现出大于2的交叉相关值，这是量子态的特征。 显示英文摘要

摘要： The realization of quantum memory using warm atomic vapor cells is appealing because of their commercial availability and the perceived reduction in experimental complexity. In spite of the ambiguous results reported in the literature, we demonstrate that quantum memory can be implemented in a single cell with buffer gas using the geometry where the write and read beams are nearly co-propagating. The emitted Stokes and anti-Stokes photons display cross-correlation values greater than 2, characteristic of quantum states, for delay times up to 4 microseconds.
