This Horizon Study describes a next-generation ground-based gravitational-wave
observatory: Cosmic Explorer. With ten times the sensitivity of Advanced LIGO, Cosmic …

MAGIS-100 is a next-generation quantum sensor under construction at Fermilab that aims to
explore fundamental physics with atom interferometry over a 100 m baseline. This novel …

Gravitational waves (GWs) were observed for the first time in 2015, one century after
Einstein predicted their existence. There is now growing interest to extend the detection …

Compared to light interferometers, the flux in cold-atom interferometers is low and the
associated shot noise is large. Sensitivities beyond these limitations require the preparation …

Squeezed light has long been used to enhance the precision of a single optomechanical
sensor. An emerging set of proposals seeks to use arrays of optomechanical sensors to …

Atom interferometers offer promising new avenues for detecting ultralight dark matter
(ULDM). The exceptional sensitivity of atom interferometers to fluctuations in the local …

In this invited review in honor of 100 years since the Stern-Gerlach (SG) experiments, we
describe a decade of SG interferometry on the atom chip. The SG effect has been a …

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

Atom interferometers with long baselines are envisioned to complement the ongoing search
for dark matter. They rely on atomic manipulation based on internal (clock) transitions or …

The sensitivity of light and matter-wave interferometers to rotations is based on the Sagnac
effect and increases with the area enclosed by the interferometer. In the case of light, the …
