“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 …

Quantum physics has intrigued scientists and philosophers alike, because it challenges our
notions of reality and locality—concepts that we have grown to rely on in our macroscopic …

Atom interferometers have been developed in the last three decades as new powerful tools
to investigate gravity. They were used for measuring the gravity acceleration, the gravity …

We simultaneously measure the gravitationally induced phase shift in two Raman-type
matter-wave interferometers operated with laser-cooled ensembles of Rb 87 and K 39 …

Presently under construction in Lund, Sweden, the European Spallation Source (ESS) will
be the world's brightest neutron source. As such, it has the potential for a particle physics …

Explaining the origin of the acceleration of the expansion of the Universe remains as
challenging as ever. In this review, we present different approaches from dark energy to …

Experiments with cold and ultracold neutrons have reached a level of precision such that
problems far beyond the scale of the present standard model of particle physics become …

We propose quantum engines powered entirely by a position-resolving measurement
performed on a quantum particle. These engines produce work by moving the quantum …

We report on precision resonance spectroscopy measurements of quantum states of
ultracold neutrons confined above the surface of a horizontal mirror by the gravity potential …

The last few decades have provided abundant evidence for physics beyond the two
standard models of particle physics and cosmology. As is now known, the by far largest part …
