AbstractECCS-0757975H. Gibbs, University of ArizonaIntellectual Merit: Solid-state entanglement on a chip is one way to describe strong coupling between a single quantum dot and a photonic crystal slab nanocavity. Unlike an atom trapped in a cavity, the quantum dot is fixed in its position within the monolithic nanocavity. Therefore, the interaction is time independent, making manipulations easier and predictable. The planar slab technology lends itself to waveguide interconnections on the chip and fiber interconnections between chips, suggesting great potential for applications in nanophotonics and quantum information science. Specific goals include deterministic placement of a single quantum dot in the antinode of the cavity field and efficient coupling of a nanocavity to a photonic crystal waveguide. These nanodevices are the technological limit of the nonlinear etalon: a single photon can control another photon. Nonlinear optics at the level of one photon and one quantum dot is exciting and should be explored and developed fully. Broader Impacts: This research will likely have an additional impact on the photonics and nanostructure industries: they hire most of our students. Under this grant two graduate students, including one African-American, will be trained in the techniques of nanotechnology and nanoscience and educated in the fundamentals of quantum optics, quantum entanglement, and quantum information science. This project will further solidify the productive collaboration with Axel Scherer's renowned photonic crystal fabrication group at Caltech. This research will contribute significantly to the knowledge base required to implement quantum information processing in the real world and improve the performance of entangled sources.

摘要ECCS-0757975H。亚利桑那大学吉布斯智力成果：芯片上的固态纠缠是描述单个量子点和光子晶体板纳米腔之间强耦合的一种方法。与被困在空腔中的原子不同，量子点被固定在整体纳米空腔内的位置。因此，交互与时间无关，使得操作更容易且可预测。平面板技术适用于芯片上的波导互连和芯片之间的光纤互连，这表明在纳米光子学和量子信息科学中具有巨大的应用潜力。具体目标包括将单个量子点确定性地放置在腔场的波腹中，以及将纳米腔与光子晶体波导有效耦合。这些纳米器件是非线性标准具的技术极限：单个光子可以控制另一个光子。一个光子和一个量子点水平的非线性光学是令人兴奋的，应该得到充分的探索和发展。更广泛的影响：这项研究可能会对光子学和纳米结构行业产生额外的影响：他们雇用了我们的大部分学生。根据这笔赠款，包括一名非裔美国人在内的两名研究生将接受纳米技术和纳米科学技术的培训，并接受量子光学、量子纠缠和量子信息科学基础知识的教育。该项目将进一步巩固与加州理工学院 Axel Scherer 著名的光子晶体制造团队的富有成效的合作。这项研究将为在现实世界中实现量子信息处理和提高纠缠源的性能所需的知识库做出重大贡献。
