Integrated Quantum Sensing Systems Based on Optically Pumped Magnetometers for Biomagnetic and Magnetic Imaging Applications

About the project

About the Project Optically Pumped Magnetometers (OPMs) are rapidly emerging as one of the most promising quantum sensing technologies for detecting ultra-weak magnetic fields with femtotesla-level sensitivity. OPM arrays have the potential to enable compact and wearable biomagnetic imaging systems, non-invasive medical diagnostics, magnetic source localization, and high-resolution non-destructive evaluation (NDE) of materials and devices. This PhD project aims to develop integrated multi-channel OPM sensing systems that combine advanced electronics, instrumentation, data acquisition, and real-time signal processing. The successful candidate will contribute to both the hardware and system-level development of next-generation OPM platforms, while exploring scientifically impactful applications in biomagnetism and magnetic imaging. Research topics may include: Integration of OPM arrays for biomagnetic sensing, including applications such as magnetocardiography (MCG), magnetomyography (MEG), or other weak biological magnetic signals. Exploration of magnetic imaging and non-destructive testing applications using OPM sensor arrays. Design of low-noise analog and mixed-signal electronics for OPM operation. Development of precision current drivers, magnetic field control systems, and multi-functional electronic modules. Implementation of multi-channel data acquisition, synchronization, and software control interfaces. Real-time signal processing, visualization, and magnetic field mapping. The project sits at the intersection of electronics engineering, quantum sensing, instrumentation, and biomedical/industrial applications. Beyond system development, the candidate will have opportunities to publish in areas such as quantum sensing instrumentation, biomagnetic imaging, magnetic field reconstruction, and advanced sensing applications.
