NIST researchers have developed a quantum receiver using Rydberg atoms that can detect and display live color television and video games. The receiver, which could be physically smaller and more tolerant of noisy environments than conventional electronics, uses atoms prepared in high-energy Rydberg states that are unusually sensitive to electromagnetic fields, including radio signals.
The team demonstrated video reception by streaming and receiving videos through the Rydberg atom sensors. They encoded a video game signal onto a carrier signal and detected it with the atoms, which was then fed directly into a TV. The researchers studied the laser beam sizes, powers, and detection methods required for the atoms to receive video in standard definition format, achieving a data rate on the order of 100 megabits per second.
