Demo proposal presents a RISC-V powered quantum sensor designed for ultra-precise magnetic field measurements even at room temperature using nitrogen-vacancy (NV) center defects in diamond. Quantum magnetometers have a wide range of applications including localization, microscopy, and system control. With RISC-V processor being integrated into the developed system, the aim is to achieve world’s most efficient sensor readout and unlock quantum sensing potential for widespread adoption. For the demonstrator, generic event-based architecture was developed, where the RISC-V plays a vital role in coordinating the hardware and provides a foundation for future miniaturization of the sensor electronics and readout ASIC design. The developed prototype enables pulsed optically detected magnetic resonance (ODMR) measurements, that provide significantly higher precision and improved experimental control in comparison to continuous-wave (CW) techniques. The goal is to showcase RISC-V powered quantum sensor with EDI (Institute of Electronics and Computer Science, Latvia) integrated setup incorporating analogue electronics for generating and sampling microwaves, digital electronics for pre-processing and control, and application-level software for users. However, even if hardware issues arise, the live demonstrator will showcase the complete RISC-V-powered quantum sensing system using the PolarFire SoC Video Kit based sensor platform. Open-source RISC-V processor grants more freedom for future ASIC implementation of the measurement system.
