Quantum emitters in diamond are a promising candidate for quantum network applications. Here, we
show basic properties of tin-vacancy (SnV) centers in diamond, which we recently discovered. The SnV
center shows a sharp zero phonon line and a high fluorescence intensity. The SnV center has a possibility
to have a long spin coherence time in the Kelvin temperature range, in contrast to other group-IV color
centers, i.e. silicon-vacancy and germanium-vacancy centers. We discuss important experiments regarding
spin and optical properties of the SnV quantum emitter for further development towards
quantum network.
