Quantum technologies with ultracold atoms for atomic clocks, interferometry and quantum simulation

超冷原子是量子技术中用于构建实用测量设备的非常有用的工具。特别令人感兴趣的是在基于量子的自主导航设备中具有应用的旋转感测设备。我们在实验量子光学和光子学组的研究计划使用量子气体，冷却到超低温，以创建玻色-爱因斯坦凝聚体（BEC）。我们的研究的关键目标之一是使用集成光学BEC干涉测量的设备的演示。一个可能的结果是将BEC技术转化为实用的导航工具。该项目将建立在我们现有的活动在斯特拉斯克莱德在原子干涉与相干物质波和工作的环形导向陷阱，以探索开发旋转传感的可扩展技术的可能性。我们将使用微加工技术（发表在Nature Nanotechnology，2013年5月：dx.doi.org/10.1038/nano.2013.47），我们已经开发了用于激光冷却装置的小型化，具有任意设计光学势的前景。本项目有两个主要方面。学生将参加EQOP小组现有的BEC干涉测量研究计划，并同时将现有知识应用于微加工设备的开发。一个关键的目标是一个集成的激光冷却和BEC干涉仪，这也可以用于量子模拟，如果光学晶格结构集成设备的演示。该项目最终将为基于芯片的BEC技术转化为实用工具提供信息。

Ultracold atoms are a very useful tool in Quantum Technologies for building practical measurement devices. Of particular interest are rotation sensing devices with applications in quantum-based, autonomous navigation devices. Our research programme in the experimental quantum optics and photonics group uses quantum gases, cooled to ultralow temperatures to create Bose-Einstein condensates (BECs).One of the key aims of our research is the demonstration of a device using integrated optics for BEC interferometry. A possible outcome would be the translation of BEC technology into a practical navigation tool. This project will build on our existing activities at Strathclyde in atom interferometry with coherent matter waves and work on ring-shaped guided traps to explore the possibilities for developing miniaturised technology for rotation sensing. We will use microfabrication technology (published in Nature Nanotechnology, May 2013: dx.doi.org/10.1038/nnano.2013.47), which we have developed for miniaturisation of laser cooling setups with the prospect for arbitrary design of optical potentials. There are two main strands to the present project. The student will participate in the existing research programmes in BEC interferometry at the EQOP group and in parallel with that apply existing knowledge in the development of a micro-fabricated device. A key aim is the demonstration of an integrated device for laser cooling and BEC interferometry, which can also be used for quantum simulation, if optical lattices structures were integrated. This project would ultimately inform the translation of chip-based BEC technology into a practical tool.
