- Abstract: Measurement sensitivity is one of the critical indicators for Rydberg atomic
radio receivers. This work quantitatively studies the relationship between the
atomic superheterodyne receiver's sensitivity and the number of atoms involved
in the measurement. The atom number is changed by adjusting the length of the
interaction area. The results show that for the ideal case, the sensitivity of
the atomic superheterodyne receiver exhibits a quantum scaling: the amplitude
of its output signal is proportional to the atom number, and the amplitude of
its read-out noise is proportional to the square root of the atom number.
Hence, its sensitivity is inversely proportional to the square root of the atom
number. This work also gives a detailed discussion of the properties of transit
noise in atomic receivers and the influence of some non-ideal factors on
sensitivity scaling. This work is significant in the field of atom-based
quantum precision measurements.

We show theoretically that it is possible to transfer vibrational excitation between trapped neutral atoms over a micrometer apart.
We find that there is a "sweet spot" where the transfer of a vibrational excitation is nearly perfect and fast compared to the Rydberg lifetime.

The best conventional radio frequency sensors still outperform Rydberg atom-based sensors with respect to sensitivity.

atom interferometer (which controls the sensitivity) can be increased by providing a larger momentum kick to the atom cloud.
One such atom optics technique involves increasing the number of central $pi-$Raman pulses.
Increased time in the intermediate high energy state results in a higher probability of undesired spontaneous decay and a loss of quantum information.

We study the noise power spectrum of the atomic receiver versus the number of atoms.
The sensitivity of the atomic receiver is limited only by the quantum noise and, in the other conditions, limited by classical noises.
This work is essential in making the sensitivity of the atomic receiver reach its ultimate limit.

Near criticality the high sensitivity of Rydberg atoms to external MW electric fields, combined with many-body enhancement induces significant changes in the optical transmission.
For continuous optical transmission at the critical point, the Fisher information is three orders of magnitude larger than in independent particle systems.

We propose an explanation based upon strong-disorder renormalization group theory.
