Microwave electric field sensing is of importance for a wide range of applications in areas of
remote sensing, radar astronomy and communications. Over the past decade, Rydberg …

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 have great potential in electric field measurement and have an advantage
with a large frequency bandwidth from the kHz to the THz scale. However, the sensitivity for …

In this work, we demonstrate the use of a Rydberg atom-based sensor for determining the
angle of arrival of an incident radio frequency (RF) wave or signal. The technique uses …

Rydberg atoms have been shown to be very useful in performing absolute measurements of
the magnitude of a radio frequency (RF) field using electromagnetically induced …

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

Up to now, the measurement of radio-frequency (RF) electric field achieved using the
electromagnetically-induced transparency (EIT) of Rydberg atoms has proved to be of high …

Rydberg atoms have been used for measuring radio-frequency (RF) electric (E)-fields due to
their strong dipole moments over the frequency range of 500 MHz-1 THz. For this …

We use a quantum sensor based on thermal Rydberg atoms to receive data encoded in
electromagnetic fields in the extreme electrically small regime, with a sensing volume over 1 …

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