Quantum entanglement has been generated and verified in cold-atom experiments and
used to make atom-interferometric measurements below the shot-noise limit. However …

An ensemble of atoms can operate as a quantum sensor by placing atoms in a
superposition of two different states. Upon measurement of the sensor, each atom is …

Quantum sensors are used for precision timekeeping, field sensing and quantum
communication,–. Comparisons among a distributed network of these sensors are capable …

Quantum sensing uses properties of quantum mechanics to go beyond what is possible with
traditional measurement techniques. In particle physics, key problems in which quantum …

Atomic high-precision measurements have become a competitive and essential technique
for tests of fundamental physics, the Standard Model, and our theory of gravity. It is therefore …

This document presents a summary of the 2023 Terrestrial Very-Long-Baseline Atom
Interferometry Workshop hosted by CERN. The workshop brought together experts from …

Several terrestrial detectors for gravitational waves and dark matter based on long-baseline
atom interferometry are currently in the final planning stages or already under construction …

We explore the possibility to overcome the standard quantum limit (SQL) in a free-fall atom
interferometer using a Bose-Einstein condensate (BEC) in either of the two relevant cases of …

The precision of matter-wave sensors benefits from interrogating large-particle-number
atomic ensembles at high cycle rates. Quantum-degenerate gases with their low effective …

We investigate the possible realization of an ultracold-atom rotation sensor that is based on
recently proposed tractor atom interferometry (TAI). An experimental design that includes the …
