A space-based quantum gas laboratory at picokelvin energy scales
Naceur Gaaloul, Matthias Meister, Robin Corgier +10
Ultracold quantum gases are ideal sources for high-precision space-borne sensing as proposed for Earth observation, relativistic geodesy and tests of fundamental physical laws as w…
Platform and environment requirements of a satellite quantum test of the Weak Equivalence Principle at the level
Christian Struckmann, Robin Corgier, Sina Loriani +6
The Space Time Explorer and QUantum Equivalence principle Space Test (STE-QUEST) recently proposed, aims at performing a precision test of the weak equivalence principle (WEP), a f…
Space-borne Bose-Einstein condensation for precision interferometry
Dennis Becker, Maike D. Lachmann, Stephan T. Seidel +32
Space offers virtually unlimited free-fall in gravity. Bose-Einstein condensation (BEC) enables ineffable low kinetic energies corresponding to pico- or even femtokelvins. The comb…
Non-linear Bragg trap interferometer
Robin Corgier, Luca Pezzè, Augusto Smerzi
We propose a scheme for trapped atom interferometry using an interacting Bose-Einstein condensate. The condensate is controlled and spatially split in two confined external momentu…
Quantum-enhanced differential atom interferometers and clocks with spin-squeezing swapping
Robin Corgier, Marco Malitesta, Augusto Smerzi +1
Thanks to common-mode noise rejection, differential configurations are crucial for realistic applications of phase and frequency estimation with atom interferometers. Currently, di…
Matter-wave collimation to picokelvin energies with scattering length and potential shape control
Alexander Herbst, Timothé Estrampes, Henning Albers +7
The sensitivity of atom interferometers depends on their ability to realize long pulse separation times and prevent loss of contrast by limiting the expansion of the atomic ensembl…
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…
Terrestrial Very-Long-Baseline Atom Interferometry: Summary of the Second Workshop
Adam Abdalla, Mahiro Abe, Sven Abend +307
This summary of the second Terrestrial Very-Long-Baseline Atom Interferometry (TVLBAI) Workshop provides a comprehensive overview of our meeting held in London in April 2024, build…
Interacting quantum mixtures for precision atom interferometry
Robin Corgier, Sina Loriani, Holger Ahlers +5
We present a source engineering concept for a binary quantum mixture suitable as input for differential, precision atom interferometry with drift times of several seconds. To solve…
Delta-kick Squeezing
Robin Corgier, Naceur Gaaloul, Augusto Smerzi +1
We explore the possibility to overcome the standard quantum limit (SQL) in a free-fall atom interferometer using a Bose-Einstein condensate (BEC) in either of the two relevant case…
Squeezing-enhanced accurate differential sensing under large phase noise
Robin Corgier, Marco Malitesta, Leonid A. Sidorenkov +6
Atom interferometers are reaching sensitivities fundamentally constrained by quantum fluctuations. A main challenge is to integrate entanglement into quantum sensing protocols to e…
Cold Atoms in Space: Community Workshop Summary and Proposed Road-Map
Ivan Alonso, Cristiano Alpigiani, Brett Altschul +246
We summarize the discussions at a virtual Community Workshop on Cold Atoms in Space concerning the status of cold atom technologies, the prospective scientific and societal opportu…
