Cryogenic Optical and Spin Characterization of Tin-Vacancy Centers in Diamond

ORAL

Abstract

Color centers in diamond are promising quantum systems that can combine long-lived spin degrees of freedom with coherent optical transitions. Recently, emitters based on Group IV-vacancy complexes, including the silicon- and germanium-vacancy, have garnered interest as their inversion symmetry protects the optical line from environmental noise. Here, we will discuss cryogenic resonant spectroscopy of tin-vacancy (SnV) center in diamond. Specifically, we will describe its electronic structure, optical signatures of spin, and coherent optical and spin properties. We find that the SnV is a candidate quantum memory that can operate at liquid helium temperatures, potentially enabling scalable quantum networks.
