1. An atom-based closed-loop control system comprising:
a compartment enclosing a gas of excited atoms comprising one or more Rydberg states, wherein the compartment is configured to be exposed to external electromagnetic radiation;
a device configured to apply an input signal to the one or more Rydberg states;
a detector configured to detect a response of the one or more Rydberg states due to an interaction of the one or more Rydberg states with the external electromagnetic radiation; and
a controller configured to automatically adjust a characteristic of the applied input signal to a set point based on, at least in part, the detected response of the one or more Rydberg states to the external electromagnetic radiation.
