Novel concepts aiming at efficient processing of information require a strong and controlled coupling of single photons with single atomic quantum systems. In this talk, I will first give an introduction to the efficient generation of single photons using planar dielectric antennas. These antennas allow us to collect the emission from an arbitrarily oriented single quantum emitter with >99%...
The Swing-UP of quantum EmitteR (SUPER) scheme utilizes two red-detuned pulses to excite a quantum system. After its theoretical prediction for a two-level system [1], the SUPER scheme was experimentally demonstrated in quantum dots [2]. To explore the full possibilities of the SUPER scheme, a two-level emitter can be embedded in a photonic cavity, which introduces new phenomena.

Since 2020, photon antibunching [1-3] and Purcell enhancement [4-5] in cavities have been observed for a variety of point defects acting as color centers in silicon. These results open the way to the development of a first deterministic source of single photons in Si (SPS), with a huge potential impact for the upscaling of integrated quantum photonics on SOI chips.
