Summary:
- Physicists have created the world's smallest light pixel, which is smaller than a grain of sand.
- This light pixel, called a "digital atom," is made up of just a few hundred atoms and can be used to store and manipulate light at the smallest possible scale.
- The development of this ultra-tiny light pixel could lead to advancements in quantum computing, communications, and other technologies that rely on the manipulation of light at the smallest scales.
