Abstract
Many applications in quantum information processing require multiple, identical quantum emitters. Among various color centers in diamond, tin-vacancy centers draw attention because of their high quantum efficiency and long spin coherence. The authors study the shifts of optical-transition frequencies of these centers in an applied electric field, and importantly find that both the linear and quadratic coefficients are orders of magnitude smaller than those of non-inversion-symmetric defects such as nitrogen-vacancy centers. This low susceptibility allows the integration of tin-vacancy centers into photonic nanostructures, which is essential for efficient spin-photon interfaces.
