Quantum technology is an emergent and potentially disruptive discipline, with the ability to
affect many human activities. Quantum technologies are dual-use technologies, and as such …

Interference with atomic and molecular matter waves is a rich branch of atomic physics and
quantum optics. It started with atom diffraction from crystal surfaces and the separated …

We simultaneously measure the gravitationally induced phase shift in two Raman-type
matter-wave interferometers operated with laser-cooled ensembles of Rb 87 and K 39 …

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 have built an atom interferometer that can measure g, the local acceleration due to
gravity, with a resolution of Δg/g= 2× 10− 8 after a single 1.3 s measurement cycle, 3× 10− 9 …

Ultracold cesium atoms are prepared in the ground energy band of the potential induced by
an optical standing wave. We observe Bloch oscillations of the atoms driven by a constant …

We report the demonstration of a Sagnac-effect atom interferometer gyroscope which uses
stimulated Raman transitions to coherently manipulate atomic wave packets. We have …

The field of experimental positronium physics has advanced significantly in the last few
decades, with new areas of research driven by the development of techniques for trapping …

We have developed a matter wave interferometer based on the diffraction of atoms from
effective absorption gratings of light. In a setup with cold rubidium atoms in an atomic …
