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。它基于我们与诺丁汉大学的合作者共同开发的一个新颖的想法。核心方面是利用激光诱导相互作用以受控且相对简单的方式产生纠缠。如果成功的话，它可能会彻底简化超冷原子的量子信息和计量学。纠缠增强计量学是一个快速发展的研究领域，其对突破精密测量电流极限的前景产生了巨大影响，其影响范围从基础测试到工业应用。然而，尽管有一些著名的原理验证实验，但在给定数量的最精确测量方面，经典方案仍然占主导地位。因此，该项目的一个特殊方面将是评估所开发的纠缠方案对于真正提高精度的适用性。与 NPL 的密切合作将增加计量研究方面的世界领先专业知识，并将该项目直接应用于计量应用的工业环境中。特别是这次合作也将为我在大学战略规划方面的发展开辟新的视角。除了精密测量应用之外，低位电子态的使用极大地限制了辐射衰变通道的数量，为研究耗散介导的纠缠开辟了整个令人兴奋的机会领域。强大的纠缠不仅可以作为计量学的资源，而且还可以作为量子计算的资源，这为资助期限之外的重要研究和职业机会提供了机会。
