Atomic receiver works with common communications signals
A new type of radio receiver sensor that uses atoms to receive commonly used communications signals has been demonstrated by researchers at the National Institute of Standards and Technology (NIST).

With further development, atom-based receivers may offer many benefits over conventional radio technologies, according to the paper. For example, there is no need for traditional electronics that convert signals to different frequencies for delivery because the atoms do the job automatically. The antennas and receivers can be physically smaller, with micrometer-scale dimensions. In addition, atom-based systems may be less susceptible to some types of interference and noise. The atom-based mixer also can measure weak electric fields precisely.

The researchers now plan to improve the new receiver by reducing laser noise and other unwanted effects.
