Microwave electric field (MW E-field) sensing is important for a wide range of applications in
the areas of remote sensing, radar astronomy and communications. Over the past decade …

Rydberg states of alkali atoms are highly sensitive to electric fields because their electron
wavefunction has a large spatial extent, leading to large polarizabilities for static fields and …

Rydberg atoms, with one highly excited, nearly ionized electron, have extreme sensitivity to
electric fields, including microwave fields ranging from 100 MHz to over 1 THz. Here, we …

We investigate the relationship between the Rabi frequency (Ω RF, related to the applied
electric field) and Autler-Townes (AT) splitting, when performing atom-based radio …

Over a hundred years later, the classic antenna, first invented by Heinrich Hertz, in 1888,, is
still the dominant technology used for the measurement of RF fields. Just seven years after …

Rydberg atoms-based electric field sensing had developed rapidly over the past decade. A
variety of theoretical proposals and experiment configurations are suggested and realized to …

With the redefinition of the International System of Units (SI) that occurred in November
2018, there has been much attention on the development of atom-based sensors for …

We demonstrate improved sensitivity of Rydberg electrometry based on electromagnetically
induced transparency (EIT) with a ground state repum** laser. Though there are many …

We discuss a fundamentally new method for electric (E) field strength (V/m) metrology
applicable to the near-field. This new approach is significantly different from currently used …

The recent developments of Rydberg atom-based sensors with the ability to measure phase
have made it possible to receive digital phase-modulated signals. In this letter, we …
