“…The reason for using atomic beams rather than cold atoms in this experiment is therefore to make the enclosed area as large as possible, 22 mm 2 in this case. From accurate measurements of the phase shift, the Earth's rate of rotation has been determined with a short term sensitivity comparable with that of the best active ring laser gyroscopes [36,37].…”

“…19 The realization of BoseEinstein condensation (BEC) of a dilute gas of trapped atoms in a single quantum state [20][21][22] has produced the matter-wave analog of a laser in optics. [23][24][25][26] Like the revolution brought about by lasers in optical interferometry, 1,27,28 it is expected that the use of Bose-Einstein condensed atoms will take the science of atom optics, particularly atom interferometry, to an unprecedented level of accuracy. [29][30][31] In addition, BEC-based coherent atom interferometry will reach its full potential in space-based applications where microgravity will allow the atomic interferometers to reach their best performance.…”

Atomic quantum sensors are a major breakthrough in the technology of time and frequency standards as well as ultraprecise sensing and monitoring of accelerations and rotations. They apply a new kind of optics based on matter waves. Today, atomic clocks are the standard for time and frequency measurement at the highest precisions. Inertial and rotational sensors using atom interferometers have already shown similar potential for replacing state-of-the-art sensors in other fields. With Bose-Einstein condensates, also referred as atom lasers, the traditional experiments with atom interferometers can be greatly improved. Testing of fundamental principles, studies of atomic properties, applications as inertial sensors, and measurements of fundamental constants can benefit from the brightness (intensity and small momentum spread) of these coherent sources. In addition, the coherence properties of condensates may allow BEC-based atom interferometers to approach the Heisenberg detection limit. This corresponds to a measurement precision which scales like 1/N for N atoms and not like 1/ √ N as for independent measurements on N atoms. We present here the recent progress toward the acheivement of new coherent atomic sources, i.e. atom lasers, that will be use in space-based atom interferometers. We introduce new concepts of atom accelerometers and gyrometers that take advantage of the high collimation and coherence properties of atoms lasers and report on the development of a 0-g coherent atom interferometer (ICE) that will be used to test the ultimate performances of atom accelerometers in space.
