Fig. 2: Tiered screening system for the identification of potentially viable host species for quantum defect implantation.
From: Identifying candidate hosts for quantum defects via data mining
a A schematic view of the process. A maximum of 0.43% of all phases in the International Crystal Structure Database were found to be potentially viable host substrates, with the most substantial reduction in candidate phases (97.3%) occurring in Stage 1 of the screening process. b Color-coded periodic table of constituent elements in viable host species depicting elements: disregarded due to the absence of spin-zero isotopes (gray); deemed too hazardous, too radioactive, too difficult to purify, and too unreactive for inclusion (red); not present in any identified phases (yellow); present largely only in cluster complex phases (blue); and present in numerous identified phases (green).
