Imagine a light switch so small it is made from just a few atoms, and so precise it releases light one particle at a time.
These tiny switches, called quantum emitters, are considered one of the core components for future technologies such as quantum computers, ultra-secure communication networks, and extremely sensitive sensors.
For years, scientists have struggled to fully understand and control them, but this won’t be the case for long. In a recent study, researchers in the US shed light on the process of identifying, designing, and placing single-photon sources with atomic precision inside ultrathin materials.
