Description
Single dopant atoms or dopant-related defect centers in a solid state matrix are of particular importance
among the physical systems proposed for quantum computing and communication, due to their potential to
realize a scalable architecture compatible with electronic and photonic integrated circuits. Here, using a
deterministic source of single laser-cooled Prþ ions, we present the fabrication of arrays of praseodymium
color centers in yttrium-aluminum-garnet substrates. The beam of single Prþ ions is extracted from a Paul
trap and focused down to 30(9) nm. Using a confocal microscope, we determine a conversion yield into
active color centers of up to 50% and realize a placement precision of 34 nm.
