级联量子光物质界面

Cascading Quantum Light-Matter Interfaces

Mehdi Namazi, Thomas Mittiga, Connor Kupchak, Eden Figueroa

摘要:

连接多个光量子设备的能力是未来量子网络发展的一个关键里程碑,未来量子网络能够共享和处理光编码的量子信息。对这些量子网络的任何节点的要求之一将是可扩展性,即使用另一个节点的输出驱动一个节点的输入的能力。在这里,我们报告的级联量子光-物质接口存储在温暖的蒸汽中的光的几个光子级脉冲,随后由检索到的字段到第二个合奏的后续存储。我们证明,即使在顺序存储后,最终的信号与背景比可以保持大于1的弱脉冲平均包含8个输入光子。

英文摘要:

The ability to interface multiple optical quantum devices is a key milestone towards the development of future quantum networks that are capable of sharing and processing quantum information encoded in light. One of the requirements for any node of these quantum networks will be cascadability, i.e. the ability to drive the input of a node using the output of another node. Here, we report the cascading of quantum light-matter interfaces by storing few-photon level pulses of light in warm vapor followed by the subsequent storage of the retrieved field onto a second ensemble. We demonstrate that even after the sequential storage, the final signal-to-background ratio can remain greater than 1 for weak pulses containing 8 input photons on average.
