We review the field of atom interferometer inertial sensors. We begin by reviewing the path
integral formulation of atom interferometers and then specialize the treatment to light-pulse …

General Relativity is today the best theory of gravity addressing a wide range of phenomena.
Our understanding of physical laws, from cosmology to local scales, cannot be properly …

We report the operation of a cold-atom inertial sensor which continuously captures the
rotation signal. Using a joint interrogation scheme, where we simultaneously prepare a cold …

The research on cold-atom interferometers gathers a large community of about 50 groups
worldwide both in the academic and now in the industrial sectors. The interest in this sub …

We present an ultrahigh-sensitivity gravimeter based on an 87 Rb atom interferometer using
stimulated Raman transitions. Compared with our previous work, a two-dimensional …

We report an improved test of the weak equivalence principle by using a simultaneous Rb
85-Rb 87 dual-species atom interferometer. We propose and implement a four-wave double …

The Zhaoshan long-baseline Atom Interferometer Gravitation Antenna (ZAIGA) is a new type
of underground laser-linked interferometer facility, and is currently under construction. It is in …

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 …

Quantum technology based on cold-atom interferometers is showing great promise for fields
such as inertial sensing and fundamental physics. However, the finite free-fall time of the …

Microgravity eases several constraints limiting experiments with ultracold and condensed
atoms on ground. It enables extended times of flight without suspension and eliminates the …
