STE-QUEST -- Space Time Explorer and QUantum Equivalence principle Space Test: The 2022 medium-class mission concept
Naceur Gaaloul, Holger Ahlers, Leonardo Badurina +45
Space-borne quantum technologies, particularly those based on atom interferometry, are heralding a new era of strategic and robust space exploration. The unique conditions of space…
Ultrabright and narrowband intra-fiber biphoton source at ultralow pump power
Alexander Bruns, Chia-Yu Hsu, Sergiy Stryzhenko +5
Nonclassical photon sources of high brightness are key components of quantum communication technologies. We here demonstrate the generation of narrowband, nonclassical photon pairs…
Tunneling Gravimetry
Patrik Schach, Alexander Friedrich, Jason R. Williams +2
We examine the prospects of utilizing matter-wave Fabry-Pérot interferometers for enhanced inertial sensing applications. Our study explores such tunneling-based sensors for the me…
Universality-of-clock-rates test using atom interferometry with scaling
Fabio Di Pumpo, Alexander Friedrich, Christian Ufrecht +1
Metric descriptions of gravitation, among them general relativity as today's established theory, are founded on assumptions summarized by the Einstein equivalence principle (EEP).…
Bragg-diffraction-induced imperfections of the signal in retroreflective atom interferometers
Jens Jenewein, Sabrina Hartmann, Albert Roura +1
We present a detailed study of the effects of imperfect atom-optical manipulation in Bragg-based light-pulse atom interferometers. Off-resonant higher-order diffraction leads to po…
Light-pulse atom interferometry with entangled atom-optical elements
Tobias Asano, Fabio Di Pumpo, Enno Giese
The analogs of optical elements in light-pulse atom interferometers are generated from the interaction of matter waves with light fields. As such, these fields possess quantum prop…
