Rapid generation and number-resolved detection of spinor Rubidium Bose-Einstein condensates
Cebrail Pür, Mareike Hetzel, Martin Quensen +5
High data acquisition rates and low-noise detection of ultracold neutral atoms present important challenges for the state tomography and interferometric application of entangled qu…
Tomography of a number-resolving detector by reconstruction of an atomic many-body quantum state
Mareike Hetzel, Luca Pezzè, Cebrail Pür +8
The high-fidelity analysis of many-body quantum states of indistinguishable atoms requires the accurate counting of atoms. Here we report the tomographic reconstruction of an atom-…
Ultracold atom interferometry in space
Maike D. Lachmann, Holger Ahlers, Dennis Becker +21
Bose-Einstein condensates (BECs) in free fall constitute a promising source for space-borne matter-wave interferometry. Indeed, BECs enjoy a slowly expanding wave function, display…
Resolution of the Co-Location Problem in Satellite Quantum Tests of the Universality of Free Fall
Sina Loriani, Christian Schubert, Dennis Schlippert +5
A major challenge common to all Galilean drop tests of the Universality of Free Fall (UFF) is the required control over the initial kinematics of the two test masses upon release d…
Quantum test of the Universality of Free Fall using rubidium and potassium
H. Albers, A. Herbst, L. L. Richardson +11
We report on an improved test of the Universality of Free Fall using a rubidium-potassium dual-species matter wave interferometer. We describe our apparatus and detail challenges a…
Preparation of mesoscopic atomic ensembles with single-particle resolution
A. Hüper, C. Pür, M. Hetzel +7
The analysis of entangled atomic ensembles and their application for interferometry beyond the standard quantum limit requires an accurate determination of the number of atoms. We…
