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-atom source and operate an atom interferometer (AI), enables us to eliminate the dead times. We show that such continuous operation improves the short-term sensitivity of AIs, and demonstrate a rotation sensitivity of 100  nrad/sec/sqrt[Hz] in a cold-atom gyroscope of 11  cm^{2} Sagnac area. We also demonstrate a…

Interleaved Atom Interferometry for High Sensitivity Inertial Measurements
We report on interleaved operation of a cold-atom inertial sensor, where three atomic clouds are simultaneously probed in an atom interferometer featuring 4 Hz sampling rate and interrogation time of
Interleaved atom interferometry for high-sensitivity inertial measurements
TLDR
This work reports on the interleaved operation of a cold-atom gyroscope, where three atomic clouds are interrogated simultaneously in an atom interferometer featuring a sampling rate of 3.75 Hz and an interrogation time of 801 ms, and proves interleaving as a key concept for future atom-interferometry sensors probing time-varying signals.
Dual matter-wave inertial sensors in weightlessness
TLDR
This work realizes simultaneous 87Rb–39K interferometers capable of operating in the weightless environment produced during parabolic flight, and constitutes a fundamental test of the equivalence principle using quantum sensors in a free-falling vehicle.
Continuous Sub-Doppler-Cooled Atomic Beam Interferometer for Inertial Sensing
We present the first demonstration of an inertially sensitive atomic interferometer based on a continuous, rather than pulsed, atomic beam at sub-Doppler temperatures in three dimensions. We
High-accuracy inertial measurements with cold-atom sensors
TLDR
The physics principle of cold-atom gravito-inertial sensors as well as the main parts of hardware and the expertise required when starting the design of such sensors are described and the progress in the development of instruments measuring gravitational and inertial signals is reviewed.
Multi-axis atom interferometer gyroscope with a single source of atoms
Using the technique of point source atom interferometry, we characterize the sensitivity of a multi-axis gyroscope based on free-space Raman interrogation of a single source of cold atoms in a glass
Extension of the rotation-rate measurement range with no sensitivity loss in a cold-atom gyroscope
A cold-atom gyroscope as an intrinsic high-precision sensor has, however, one inevitable limitation for its dynamic application lying in the vanishing fringe contrast beyond the rotation-rate limit.
