Abstract
Quantum magnetometry is a promising technology for sensitive magnetic field sensing that has a wide range of applications. Unfortunately, this technology is very cost-intensive and size-limiting in many real-world applications. Consequently, this pioneering technology has found little use outside the lab. The aim of this research is to create a compact and fully integrated LED quantum magnetometer based on nitrogen-vacancy centers in diamond microcrystals that will allow for the commercialization of quantum magnetometers. Due to recent strides in the field of quantum magnetometry, integrated quantum sensors can be miniaturized to a degree that would allow them to be viable in applications they were not previously. Using research from the University of Münster (Pogorzelski et al, 2024) we aim to build off their approach and integrate our quantum magnetometer onto a PCB in the form of a modular Arduino R4 Uno shield that allows it to be easily implemented into many systems. We aim to do this by replacing external signal processing hardware required with current systems with sequential Bayesian estimation code run on the Arduino R4 Uno. The sensor and required signal amplifiers and drivers for the sensor are integrated into a single PCB board that can be attached to the Arduino as a module. Once constructed this PCB system will be tested with existing lab results on quantum magnetometers to deem its sensitivity viable with our intended goals.
