Abstract
Section titled āAbstractāAtomicāscale impurity spins, also called color centers, in an otherwise spināfree diamond host lattice have proven to be versatile tools for applications in solidāstateābased quantum technologies ranging from quantum information processing (QIP) to quantumāenhanced sensing and metrology. Due to its wide band gap, diamond can host hundreds of different color centers. However, their suitability for QIP or sensing applications has only been tested for a handful of these, with the nitrogen vacancy (NV) strongly dominating this field of research. Due to its limited optical properties, the success of the NV for QIP applications however strongly depends on the development of efficient photonic interfaces. In the past years the negatively charged silicon vacancy (SiV ā ) center received significant attention due to its highly favourable spectral properties such as narrow zero phonon line transitions and weak phonon sidebands. Here, the recent work investigating the SiV centerās orbital and electron spin coherence properties is reviewed as well as techniques to coherently control its quantum state using microwave as well as optical fields. Also, potential future experimental directions to improve the SiVās coherence time scale and to develop it into a valuable tool for QIP applications are outlined.
