Silicon-vacancy (SiV) color centers in diamonds have emerged as one of the most promising platforms for quantum communication, quantum information processing, and quantum networks because of their special optical and spin characteristics. Inversion symmetry, which distinguishes the SiV* center from other color centers, results in extremely stable optical transitions with little spectral diffusion. Their ability to produce indistinguishable single photons, a crucial prerequisite for scalable quantum networks, makes them perfect candidates. Additionally, it is possible to represent the SiV* core as a two-level quantum system, which allows for coherent single-photon control and manipulation. SiV* centers can be coupled to optical cavities and waveguides.
Thanks to recent developments in nanofabrication and photonic integration, which are greatly improving spin-photon coupling efficiency.
