This topical review addresses how Rydberg atoms can serve as building blocks for
emerging quantum technologies. Whereas the fabrication of large numbers of artificial …

Atom-based measurements of length, time, gravity, inertial forces and electromagnetic fields
are receiving increasing attention. Atoms possess properties that suggest clear advantages …

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 …

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 …

Quantum transducers that can convert quantum signals from the microwave to the optical
domain are a crucial optical interface for quantum information technology. Coherent …

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 …

Terahertz (THz) near-field imaging is a flourishing discipline 1, 2, with applications from
fundamental studies of beam propagation 3 to the characterization of metamaterials 4, 5 and …

We discuss a fundamentally new approach for the measurement of electric (E) fields that will
lead to the development of a broadband, direct SI-traceable, compact, self-calibrating E-field …

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 …

The main objective of quantum simulation is an in-depth understanding of many-body
physics, which is important for fundamental issues (quantum phase transitions, transport,…) …
