Open-source FPGA control for Nitrogen-Vacancy Quantum Sensing*

The recent release of radio frequency system on chip (RFSoC) FPGA boards opens an opportunity for researchers to implement cheap, fast, custom hardware for quantum sensing, quantum information processing, or complex measurements requiring high precision timing. This has recently been demonstrated through the Quantum Instrumentation Control Kit (QICK) [1] firmware for superconducting qubit control. In this talk, I will show how the QICK framework can be further utilized for nitrogen-vacancy magnetometry from single defects to ensembles. Using our QICK extension, (Defect Arbitrary Waveform Generation, DAWG) can reduce the cost of defect-based quantum sensing and information processing by nearly a factor of 10 but will also enable techniques that are infeasible or impossible with traditional instruments, such as real time feedback for adaptive pulse sequencing.  [1] Stefanazzi, L. et al.
