内容記述 |
Qubit technologies using nitrogen-vacancy color centers in diamond require precise knowledge of the centers, including the number of emitters within a diffraction-limited spot and their orientation. However, the number of emitters is challenging to determine when there is finite background, which affects the precision of resulting quantum protocols. Here we show the photoluminescence (PL) intensity and quantum correlation (Hanbury Brown and Twiss) measurements as a function of polarization for one- and two-emitter systems. The sample was made by implanting low concentrations of adenine (C5H5N5) into a low nitrogen chemical vapor deposition diamond. This approach yielded well-spaced regions with few nitrogen-vacancy centers. By mapping the PL intensity and quantum correlation as a function of polarization, we can distinguish two emitter systems from single emitters with background, providing a method to quantify the background signal at implanted sites, which might be different from off-site background levels. This approach provides a valuable new mechanism for characterizing few emitter systems useful for quantum sensing, communication, and computation tasks. |
