Australian NV & Other Defect Centers Community Seminar
May 6 @ 3:00 pm - 4:30 pm
Research in the field of NV and other defect centers has made great progress in recent years. However, as science progresses, the instruments and software researchers use for controlling their quantum systems is becoming a real bottleneck and a limiting factor on what experiments you can practically run at the lab, and in a reasonable time.
In this seminar we want to have an in-depth look at how challenging experiments, which can easily have taken months of work to set up (developing hardware and software, programming FPGAs, synchronizing and patching together devices), can be now run very easily, and with short segments of code.
The Quantum Orchestration Platform (QOP) combines waveform generation, acquisition, and data-processing in real-time. This paves the way to advanced experiments utilizing fast-feedback (<200 ns) and dynamic control flow. We want to demonstrate how this enables adaptive sensing and active nuclear spin initialization with only a few lines of code. For this purpose, we will give a detailed presentation of the implementation of two NV experiments with the QOP. First, we will discuss adaptive sensing using real-time Bayesian estimation. Here, real-time feedback is used to significantly enhance the signal-to-noise ratio. The second presented experiment is enhanced NMR utilizing a long-living memory spin to prolong the achieved correlation times. The shown implementation includes techniques like room temperature single-shot readout and active nuclear spin initialization.
