Abstract

Diamond is host to color centers, an interesting type of quantum system. Examples are the well-studied nitrogen-vacancy center and more recent the group-IV color centers. These systems show promising attributes for quantum communication applications, e.g. long coherence times of individually addressable spins that couple to optical transitions [1].

Group IV color centers in nanodiamonds

Richard Waltrich

Color Centers in Diamond have great potential to be used as a source for quantum optic applications. Using nanodiamonds as a host material can improve physical properties and opens new possibilities for integration into hybrid systems. This theses explores fundamental properties of Group-IV color centers in nanodiamonds and their integration into photonic platforms such as microcavities, bullseye antennas and photonic crystal cavities.

Recent progress in hybrid diamond photonics for quantum information processing and sensing

Ryota Katsumi, Kosuke Takada, Fedor Jelezko +1 more

Point defects in diamond, particularly nitrogen-vacancy (NV) centers, have emerged as powerful tools for a broad range of quantum technologies. These defects are promising candidates for quantum information science, serving as deterministic single-photon sources and solid-state quantum memories. They have also been employed as nanoscale quantum sensors to detect various physical quantities, including magnetic fields, electric fields, and temperature, owing to their long spin coherence time at room temperature. Development of these diamond-based quantum technologies has been rapidly boosted by a recent quantum leap in nanofabrication technologies for high-quality single-crystal diamond. Incorporating these color centers into diamond nanostructures with mature integrated photonics provides a promising route to build scalable and practical systems for quantum applications. This review discusses recent progress and challenges in the hybrid integration of diamond color centers on cutting-edge photonic platforms.
