Rapid Characterization of Spin Qubit Systems Using Open Source Resources*

Nitrogen-vacancy (NV) centers in diamond have garnered significant attention due to their room temperature operation, long spin coherence, and potential in quantum sensing and other quantum technologies. With growing interest in a variety of experimental applications, efficient characterization of these material systems is required to meet demand and continued development. Thus, there is a growing need for automated rapid optical characterization experiments which reduce the monetary and temporal costs associated with conventional measurement techniques on traditional hardware. Here we present an approach to address the rapid characterization challenges of NV centers in diamond through simplified instrumentation and optics based on open-source hardware and software. We integrate cost-effective RF control and timing electronics capable of automated quantum control of the NV center spin, open-source computer control software, and minimal optics for rapid characterization of spin qubits in diamond.
