National Institute of Standards and Technology (NIST) researchers have developed an ‘Atomic Television’ that is based on their atom-based radio receiver capable of displaying live color video and games. Technically speaking, it uses rubidium atoms in a Rydberg state as receivers.
A stable radio signal is then applied to the glass container filled with atoms in a Rydberg state and the modulated output is then fed to a television where an analog-to-digital converter transforms the signal into a video graphics array format for display. What the researchers discovered was that the beam size affects the average time the atoms remain in the laser interaction zone and that a shorter time as well as a smaller beam produce more data. A small beam diameters (less than 100 micrometers) for both lasers meant much faster responses and color reception. Speaking of atoms, did you know that physicists have developed a quantum microphone capable of detecting individual sound particles at an atomic level?

We figured out how to stream and receive videos through the Rydberg atom sensors. Now we are doing video streaming and quantum gaming, streaming video games through the atoms. We basically encoded the video game onto a signal and detected it with the atoms. The output is fed directly into the TV,” said Chris Holloway, NIST project leader.
