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

“Quantum sensing” describes the use of a quantum system, quantum properties, or quantum
phenomena to perform a measurement of a physical quantity. Historical examples of …

Highly sensitive phase-and frequency-resolved detection of microwave electric fields is of
central importance in a wide range of fields, including cosmology,, meteorology …

Interacting many-body systems display enhanced sensitivity close to critical transition points
due to diverging quantum fluctuations. This criticality-based enhancement has been …

Quantum information processing based on Rydberg atoms emerged as a promising
direction two decades ago. Recent experimental and theoretical progresses have shined …

Atomtronics deals with matter-wave circuits of ultracold atoms manipulated through
magnetic or laser-generated guides with different shapes and intensities. In this way, new …

We demonstrate an atomic rf receiver and spectrum analyzer based on thermal Rydberg
atoms coupled to a planar microwave waveguide. We use an off-resonant rf heterodyne …

We present an object-oriented Python library for the computation of properties of highly-
excited Rydberg states of alkali atoms. These include single-body effects such as dipole …

The coupling of microwave and optical systems presents an immense challenge due to the
natural incompatibility of energies, but potential applications range from optical …

The second quantum revolution hinges on the creation of materials that unite atomic
structural precision with electronic and structural tunability. A molecular approach to …
