Abstract

The INTENTAS project aims to develop an atomic sensor utilizing entangled Bose-Einstein condensates (BECs) in a microgravity environment. This key achievement is necessary to advance the capability for measurements that benefit from both entanglement-enhanced sensitivities and extended interrogation times. The project addresses significant challenges related to size, weight, and power management (SWaP) specific to the experimental platform at the Einstein-Elevator in Hannover. The design ensures a low-noise environment essential for the creation and detection of entanglement. Additionally, the apparatus features an innovative approach to the all-optical creation of BECs, providing a flexible system for various configurations and meeting the requirements for rapid turnaround times. Successful demonstration of this technology in the Einstein-Elevator will pave the way for a future deployment in space, where its potential applications will unlock high-precision quantum sensing.

INTENTAS——用于微重力的纠缠增强原子传感器

INTENTAS项目旨在开发一种在微重力环境下利用纠缠玻色-爱因斯坦凝聚物（BECs）的原子传感器。这一关键成果对于提高测量能力是必要的，这些测量能力受益于纠缠增强的灵敏度和延长的询问时间。该项目解决了汉诺威爱因斯坦电梯实验平台在尺寸、重量和电源管理（SWaP）方面的重大挑战。这种设计确保了低噪声环境对产生和检测纠缠至关重要。此外，该设备还采用了一种创新的方法来创建全光学BECs，为各种配置提供灵活的系统，并满足快速周转时间的要求。这项技术在爱因斯坦电梯上的成功演示将为未来在太空中的部署铺平道路，其潜在应用将解锁高精度量子传感。
