• Abstract: Light-pulse atom interferometers are highly sensitive to inertial and gravitational effects. As such they are promising candidates for tests of gravitational physics. In this article the state-of-the-art and proposals for fundamental tests of gravity are reviewed. They include the measurement of the gravitational constant $G$, tests of the weak equivalence principle, direct searches of dark energy and gravitational-wave detection. Particular emphasis is put on long-time interferometry in microgravity environments accompanied by an enormous increase of sensitivity. In addition, advantages as well as disadvantages of Bose-Einstein condensates as atom sources are discussed.

  We consider a Bose-Einstein condensate interacting with a gravitational wave for the case when the gravitational fluctuations are quantized. We observe that the solution of the time-dependent part of the pseudo-Goldstone boson has infusions from the noise induced by gravitons. We observe the effect of decoherence due to interacting phonon modes in the quantum gravitational Fisher information.

• Measuring gravity by holding atoms [0.0]
  We optimize sensitivity of a lattice interferometer and use a system of signal inversions and switches to suppress and quantify systematic effects. This enables us to measure the attraction of a miniature source mass, ruling out the existence of screened dark energy theories. Further upgrades may enable measuring forces at sub-millimeter ranges, the gravitational Aharonov-Bohm effect and the gravitational constant, compact gravimetry.

• Gravitational waves affect vacuum entanglement [68.8204255655161]
  The entanglement harvesting protocol is an operational way to probe vacuum entanglement. Using this protocol, it is demonstrated that while the transition probability of an individual atom is unaffected by the presence of a gravitational wave, the entanglement harvested by two atoms depends sensitively on the frequency of the gravitational wave. This suggests that the entanglement signature left by a gravitational wave may be useful in characterizing its properties, and potentially useful in exploring the gravitational-wave memory effect and gravitational-wave induced decoherence.

• Proposal for an optical interferometric measurement of the gravitational red-shift with satellite systems [52.77024349608834]
  Einstein Equivalence Principle (EEP) underpins all metric theories of gravity. The iconic gravitational red-shift experiment places two fermionic systems, used as clocks, in different gravitational potentials. A fundamental point in the implementation of a satellite large-distance optical interferometric experiment is the suppression of the first-order Doppler effect. We propose a novel scheme to suppress it, by subtracting the phase-shifts measured in the one-way and in the two-way configuration between a ground station and a satellite.
