论文摘要
量子信息的受控操作，存储和检索对于量子通信和计算至关重要。光原子样品作为储存介质实现的光的量子记忆对于它们的高储存效率和寿命而言是突出的。我们在这样的存储系统中证明了在1：2 mm上存储的光的受控运输，并证明了传输过程及其动力学仅对存储的连贯性有很小的影响。将提出的概念扩展到更长的传输距离并增加存储部分的数量将允许开发新颖的量子设备，例如光赛车记忆或光学量子登记册。
Controlled manipulation, storage and retrieval of quantum information is essential for quantum communication and computing. Quantum memories for light, realized with cold atomic samples as the storage medium, are prominent for their high storage efficiencies and lifetime. We demonstrate the controlled transport of stored light over 1:2 mm in such a storage system and show that the transport process and its dynamics only have a minor effect on the coherence of the storage. Extending the presented concept to longer transport distances and augmenting the number of storage sections will allow for the development of novel quantum devices such as optical race track memories or optical quantum registers.
