They say no two are alike\dots{} Inversion-symmetric fluorescent color centers in diamonds, such as the germanium vacancy, desirable for solid-state single-photon emitters integrated quantum systems, but their complex mesoscopic environments make it challenging to obtain multiple $i\phantom{\rule{0}{0ex}}d\phantom{\rule{0}{0ex}}e\phantom{\rule{0}{0ex}}n\phantom{\rule{0}{0ex}}t\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}c\phantom{\rule{0}{0ex}}a\phantom{\rule{0}{0ex}}l$ emitters. These experiments use large strain gradient a diamond microcantilever align spectra of vacancies within 50-nm spot. This approach makes possible identical diamond.
