1. A quantum-sensing radiofrequency receiver system comprising:
plural channels, each channel containing molecular entities, the molecular entities of each cell being hermetically sealed within a respective cell, a first channel containing the molecular entities hermetically sealed within a first cell, each of the molecular entities having plural Rydberg states;
a laser system for exciting the molecular entities of each channel to Rydberg states using a respective probe laser beam and at least one respective coupling laser beam;
a photodetector system for tracking a respective intensity of each respective probe laser beam after it passes through the molecular entities of a respective channel; and
a tuning system for tuning each channel by altering a resonance frequency for transitions between Rydberg states of the molecular entities of the channel so that different channels are tuned to respectively different frequencies.
