Rydberg sensor having rydberg sensing regions with at least one optical amplifier and associated methods

A Rydberg sensor comprising:

• a plurality of Rydberg sensing regions;
• a probe laser source;
• an optical path extending from the probe laser source to feed the plurality of Rydberg sensing regions in a series configuration;
• and
• a plurality of optical amplifiers for the probe laser source coupled within the optical path between a plurality of adjacent pairs of Rydberg sensing regions.

A method for receiving a Radio Frequency (RF) signal comprising:

• exposing a plurality of Rydberg sensing regions to the RF signal;
• operating a probe laser source coupled to an optical path extending from the probe laser source to feed the plurality of Rydberg sensing regions in a series configuration;
• and
• operating at least one optical amplifier for the probe laser source coupled within the optical path between at least one adjacent pair of Rydberg sensing regions.
