Light Storage in Atomic Coherences: New Protocols and Applications

以下的建议涉及光与量子化介质之间的相干绝热相互作用的实现、研究和应用。特别是，我们的目标是在原子相干光存储的应用程序，由电磁感应透明（EIT）驱动。我们提出了调查的二维信息（即图像）的存储在原子相干，驱动在主晶体中的镨掺杂剂。与气相相比，掺杂的固体允许更长的存储时间和存储效率。此外，该介质提供了可扩展性。我们计划结合联合收割机图像存储在原子相干动态退相干控制和反馈控制脉冲整形，涉及进化算法。强大的技术相结合，允许提高存储时间和存储效率的原子相干的数量级。第一个可行性研究支持这些期望。除了EIT，我们还提出了应用受激拉曼绝热通道（STIRAP）来驱动逻辑运算。这也可以为光学并行处理提供可能性。总之，这些项目旨在显著扩展光存储领域的最新技术，光学驱动逻辑的新概念，以及将强大的光学技术与新应用相结合。

The following proposal deals with the implementation, investigation and application of coherent- adiabatic interactions between light and quantized media. In particular, we aim at applications of light storage in atomic coherences, driven by electromagnetically-induced transparency (EIT). We propose investigations on storage of two-dimensional information (i.e. images) in atomic coherences, driven in Praseodymium dopants in a host crystal. In contrast to the gas phase, doped solids permit much larger storage times and storage efficiencies. Moreover, the medium offers scalability. We plan to combine image storage in atomic coherences with dynamic decoherence control and feedback-controlled pulse shaping, involving evolutionary algorithms. Combination of the powerful techniques permits the enhancement of storage times and storage efficiencies in atomic coherences by orders of magnitude. First feasibility studies support these expectations. In addition to EIT, we also propose the application of stimulated Raman adiabatic passage (STIRAP) to drive logic operations. This may also provide possibilities for optical parallel processing. In summary, the projects aim at a significant extension of the state-of-the-art in light storage, novel concepts for optically-driven logics, and combination of powerful optical technologies towards novel applications.
