How big is a visible photon?
This video is actually not about photon size but about coherence length. In this video I discuss the behavior of electromagnetic radiation, especially the aspect of interference. The experiment shows that there is no such thing as individual photons in EM radiation. The photon only exists as an energy exchange between radiation and matter. 0:00 ...

Quantum Computing & Tech ⚛️ on Instagram: "Sean Carroll demonstrates just how deeply strange quantum reality is—using a single photon. In a lab in Geneva, a photon is fired at a partially silvered mirror. According to quantum mechanics, it doesn’t choose a path. It both reflects and passes through at the same time, existing in a superposition of outcomes. Detectors on each path then register the result, creating two distinct physical possibilities. Until a measurement is made, neither outcome is
