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.

超电原子是用于构建实用测量设备的量子技术中非常有用的工具。特别令人感兴趣的是旋转传感设备，并具有基于量子的自主导航设备中的应用。我们在实验量子光学和光子学组中使用的研究计划使用量子气，冷却至超低温度来创建Bose-Einstein冷凝物（BEC）。我们研究的关键目的之一是使用集成的Optics进行BEC干涉仪来证明设备。可能的结果将是将BEC技术转换为实用导航工具。该项目将基于我们在Atom干涉率的Strathclyde的现有活动与连贯的物质波，并在环形引导的陷阱上进行工作，以探索开发用于旋转传感的小型化技术的可能性。我们将使用微生物技术（在自然纳米技术上发表，2013年5月：dx.doi.org/10.1038/nnano.2013.47），我们已经开发了用于小型的激光冷却设置，并具有对光电位的任意设计的前景。本项目有两个主要链。该学生将参加EQOP组的BEC干涉学研究计划，并同时将现有知识应用于微型设备的开发中。一个关键目的是演示用于激光冷却和BEC干扰法的集成装置，如果集成了光学晶格结构，也可以用于量子模拟。该项目最终将为基于芯片的BEC技术翻译成一种实用工具。
