项目摘要

This project is about developing quantum information tools for precision measurements. It is based on a novel idea, which we developed together with our collaborators at Nottingham University. The central aspect is to use laser induced interactions to create entanglement in a controlled and relatively simple way. If successful it might bring radical simplifications to quantum information and metrology with ultracold atoms. Entanglement enhanced metrology is a rapidly growing field of research which owes its high impact to the prospect of beating current limits in precision measurement with implications ranging from fundamental tests to industrial applications. However, despite some prominent proof-of-principle experiments, classical schemes are still prevailing when it comes to the most precise measurement of given quantity. A particular aspect of this project will thus be the assessment of the suitability of the developed entanglement scheme for a real enhancement of precision. A close collaboration with NPL will add world leading expertise in metrology research and put the project into direct industrial context with regards to metrology applications. In particular this collaboration will also open new perspectives for my development with regards to the strategic plans of the University. In addition to the precision measurement application, the use of low-lying electronic states drastically limits the number of radiative decay channels opening an entire field of exciting opportunities to study dissipation-mediated entanglement. The prospect of robust entanglement as a resource not only for metrology, but also for quantum computation opens significant research and career opportunities beyond the duration of the grant.

该项目旨在开发用于精确测量的量子信息工具。它是基于一个新颖的想法，我们与诺丁汉大学合作者一起发展。中心方面是使用激光诱导的相互作用以一种相对简单的方式创建纠缠。如果成功的话，它可能会给超低原子带来量子信息和计量学的根治性简化。纠缠增强的计量学是一个快速增长的研究领域，其高影响力归功于在精确测量中击败当前限制的前景，其影响从基本测试到工业应用。然而，尽管有一些突出的原理实验证明，但在对给定数量的最精确测量方面，经典方案仍在流行。因此，该项目的一个特定方面将是评估开发的纠缠方案的适用性，以实现精确的真正增强。与NPL的密切合作将增加世界领先的计量研究专业知识，并将该项目与计量应用有关。特别是，这种合作还将为我在大学的战略计划方面的发展开辟新的观点。除了精确的测量应用外，低洼电子状态的使用极大地限制了辐射衰减通道的数量，为研究耗散介导的纠缠而开辟了整个令人兴奋的机会。强大的纠缠不仅是计量学的资源，而且对量子计算的资源的前景为超出了赠款期限的大量研究和职业机会。
