Researchers at the National Institute of Standards and Technology (NIST) have adapted their atom-based radio receiver to detect and display live color television and video games.
Atom-based communications systems are of practical interest because they could be physically smaller and more tolerant of noisy environments than conventional electronics. Adding video capability could enhance radio systems in, for example, remote locations or emergency situations.
NIST’s receiver uses atoms prepared in high-energy “Rydberg” states, which are unusually sensitive to electromagnetic fields, including radio signals. These sensors also enable signal power measurements linked to the international system of units (SI). The latest work, described in AVS Quantum Science, is the first to demonstrate video reception.
