Abstract The concept of photon counting is already a century old. However, we have only managed to harness its power over the last few decades. Generating and detecting these single quanta of light energy is essential for many applications and disruptive technologies that will solve many of today's global challenges, from super‐efficient photonic quantum processors and ultrasecure communication to highly accurate sensors for biomedical imaging. Single‐photon generation and detection technologies are redesigning the map of photonics applications.
