One-Shot Magnetometer

原子量子态前所未有的精度和可重复性使它们成为理想的惯性传感器。这个项目将使用原子自旋极化的进动来测量外部磁场的大小和排列。与传统的原子磁强计不同，我们将用矢量涡旋光照射原子蒸气，以获得空间变化的信号，从中我们可以确定磁场。该项目结合了对基本矢量光-物质相互作用的探索，最先进的光整形和紧凑型量子技术仪器的开发，与EPSRC量子技术主题密切相关。该项目由Fraunhofer应用光子学中心作为QuantIC学生奖学金的一部分提供支持。

The unprecedented precision and reproducibility of atomic quantum states makes them ideal inertial sensors. This project will use the precession of atomic spin polarisation to measure the magnitude and alignment of an external magnetic field. Unlike conventional atomic magnetometers which require the time-dependent detection of this precession, we will illuminate an atomic vapour with vector vortex light to obtain a spatially varying signal from which we can determine the magnetic field. The project combines exploration of fundamental vectorial light-matter interaction, state-of-the-art light shaping and the development of a compact quantum technological instrument, closely aligned with the EPSRC quantum technology theme. The project is supported by the Fraunhofer Centre for Applied Photonics as part of a QuantIC studentship.
