One of the most promising technologies for future quantum circuits are photonic circuits, i.e. circuits based on light (photons) instead of electrons (electronic circuits). First, it is necessary to create a stream of single photons and control their direction. Researchers have now succeeded in creating a steady stream of photons emitted one at a time and in a particular direction.
