Rydberg-sensor can make a new form for electromagnetic sensors.

Rydberg-sensor can detect the entire radio spectrum. And that kind of sensor would revolutionize radio technology in the civil and military fields. What would radio astronomers do with sensor, what can detect all radio spectrum? Or what kind of ECM (Electronic Countermeasure System) can be done, if the system can observe the entire radio spectrum. 

Rydberg-sensor means sensor what benefits Rydberg-atoms. That kind of quantum sensor uses the atoms, where the electrons that are orbiting the most out trajectories are in the high excitation level and that thing makes it possible to detect the oscillation of all radio frequencies.

 But the thing is that there is a long path to go that the Rydberg sensor can even go to field test. The Rydberg sensor uses the laser rays for adjusting atoms in Rydberg-position and that kind of electromagnetic sensors can use the interaction of electromagnetic fields to detect the radio signals. When the radio signal impacts the quantum field or the outer electrons of the Rydberg-atoms and the interaction can be noticed by sensors.

When the radio wave will hit the electric field that energy is jumping out from the electron and in that case. The electron must release the extra energy by sending photons. And those photons can be noticed by the photoelectric sensor. It's not important does the radio wave effects straight to electron, or the quantum field around the atom. The thing that matters is that the radiation will increase the energy level of the Rydberg-atoms or sharper saying the high-energy electrons in the most out trajectories. 

The reason for that is that because the outer electrons in the Rydberg-atoms are at the high-energetic excitation level. The small increase in the energy to the electron causes the increase of the quantum field. So the electron in the quantum field will be acting as the radio amplifier.
