Systematic Search for New Color Centers in Diamond for Quantum Technologies
Abstract
The goal of this YIP was to systematically search for new color centers in diamond that will act as bits for storing and processing quantum information. Color centers in diamond are atomic scale defects in diamond with energetically deep, confined electronic states that can have exceptional spin and optical coherence. In particular, the nitrogen vacancy (NV) center in diamond has been widely deployed in many recent experiments in quantum science, and is actively explored for quantum sensing and network technologies. However, known color centers suffer from either poor optical coherence or poor spin coherence, motivating a search for alternative color centers that are less sensitive to their environment. Prior work on new defects in diamond has relied on serendipitous discovery. Our approach, by contrast, is to systematically search for new color centers in diamond by introducing heteroatoms through ion implantation into ultrahigh purity, CVD diamonds, using thermal annealing to remove ion implantation damage, and to characterize the resulting color centers with bulk spin and optical spectroscopy techniques that are optimized for interrogating thin layers of implanted defects. We then perform detailed single center spectroscopy on defects that display promising properties.
