Solitary defects with quantum mechanical states mimicking those of trapped ions have been delivering many breakthroughs in quantum information science and technologies. Recent works report discoveries of multiple new defects in a wide range of materials, indicating that the phase space for defect-derived quantum functionality is truly vast. However, to date, quantum defect research has primarily relied on serendipitously discovered, naturally formed defects that not only distribute randomly in host materials but also exhibit diverse optical and quantum coherence properties. As a result, integration of defects into electronic/photonic nanodevices – an essential step for realizing most QIS technologies – can only be achieved by very complex, costly, and time consuming approaches that place a bottleneck on the progress of QIS research. Center for integrated nanotechnologies is developing two complementary capabilities for deterministic implantation of quantum defects in ranges of host materials. The first top-down approach is based upon focused ion beam technology. In the second bottom-up approach, Covalent functionalization chemistry will be combined with scanning probe microscopy to develop deterministic chemical implantation chemistry. Here in this talk I will report recent progress we made toward these deterministic quantum defect creation approaches in 1D single walled carbon nanotubes 2D transition metal dichalcogenide and hexagonal boron nitride monolayers.
