Quantum Control of Gravity with Levitated Mechanics

QuCoM的主要目标是证明悬浮加速度传感器的概念验证（TRL 1）及其在量子控制状态下检测小质量重力的能力。为了实现这一目标，我们将探讨量子力学和引力之间的相互作用，在一个参数范围内，成本效益的桌面实验。我们将在光学和磁性陷阱中悬浮亚毫米粒子，并使用它们来探测前所未有的质量体系中的引力。此外，我们将研究量子叠加，其中这些质量是离域的。我们将讨论一些最流行的理论建议结合量子物理学和重力在一个非标准的方式。拟议的实验将评估其有效性的限制和/或进一步限制其参数的值。该联盟由两名实验者，两名理论家和两名SME组成，以解决这一目标。有关实验将根据该联盟合作伙伴的实验专业知识，利用光学和磁性捕获的微/纳米粒子进行。在南安普顿进行的悬浮力学实验已经被欧盟创新雷达发现。在QuCoM中，我们将超越并展示双质量重力传感以及我们的传感器在量子域中的操作。状态准备、控制和分析方案基于理论合作伙伴的专业知识。QuCoM的合作伙伴高科技中小企业将帮助优化实验设备，以实现预定目标，这反过来又将使他们能够向市场提供他们改进的亚mK低振动低温设备产品。SME LSI将与莱顿大学一起探索将我们的技术实施到微型卫星平台中的可行性，以利用重力探测进行天基计量和地球探测。这是我们直接的技术影响和创新案例。

The main objective of QuCoM is to demonstrate the proof of concept (TRL 1) of a levitated acceleration sensor and its ability detecting gravity of small masses and in the quantum controlled regime. Toward this objective we will explore the interplay between quantum mechanics and gravity in a parameter range accessible for cost-effective table-top experiments. We will suspend sub millimetre particles in optical and magnetic traps and use those to detect gravitational forces in an unprecedented mass regime. Also, we will investigate quantum superpositions in which these masses are delocalized. We will address some of the most popular theoretical proposals combining quantum physics and gravity in a nonstandard fashion. The proposed experiments will assess their limits of validity and/or further constrain the values of their parameters. The consortium consists of two experimentalists, two theorists, and two SMEs to address the objective. The experiments in question will be performed with optically and magnetically trapped micro/nano-particles based on the experimental expertise of partners in the consortium. Levitated mechanics experiments at Southampton have been already picked up by the EU Innovation radar. In QuCoM we will, go beyond and demonstrate the two-mass gravity sensing as well as the operation of our sensors in the quantum domain. The state preparation, control and analysis schemes are based on the expertise of the theory partners. QuCoM partner high-tech SMEs will help to optimize the experimental apparatus for fulfilment of the targeted objectives, which will in turn put them in a position to offer their improved products in sub mK, low vibration cryogenic equipment to market. The SME LSI will explore, together with University of Leiden, the feasibility of implementing our technology into a micro-satellite platform for space based metrology and Earth Exploration utilizing gravitational detection. This is our direct technology impact and innovation case.
