Abstract : We report two Quantum Atom Optics experiments : the atomic Hong-Ou-Mandel experiment and preliminary results toward Bell's inequality test on momentum of two atoms. Both experiments reveal interesting behaviors of matter. The first one shows a 2-particle interference and the second one suggests entanglement momenta between two atoms. These aspects of quantum mechanics are really surprising and unintuitive. Realizing these experiments with a few atoms in a controlled environment are necessary to strengthen our understanding of the world, particularly when quantum mechanics and gravitation act simultaneously.
