X-ray nanoprobe strain measurements for diamond-based quantum sensing
ORAL
Abstract
Point defects in diamond are a popular, growing platform for quantum sensing and information. Nanoscale strain is a crucial challenge for many such applications, including high-resolution magnetometry and quantum information processing with fabricated optical devices. Additionally, measuring nanoscale strain is central to a proposed diamond-based technique for directional detection of dark matter. Scanning Bragg diffraction allows three-dimensional measurements of strain at the nanoscale. We discuss the application of this technique to lab-grown diamonds, including measurements of growth-defect-induced strain in a diamond optimized for magnetic sensing and background characterization measurements for a proposed dark matter detector.
