A long-standing challenge in the field of quantum physics is the efficient synchronization of individual and independently generated photons (i.e., light particles). Realizing this would have crucial implications for quantum ...
The interactions between light and matter are a central research focus in the field of photonics. Resonant cavities with high quality factors (Q) are capable to confine light effectively and exhibit ultra-long radiation lifetimes, ...
