Balancing Quasi-Bragg Regime and Velocity Selectivity in Quantum-Enhanced Atom Interferometry
Christian Miguel Karres, Daniel Derr, Enno Giese
Spin squeezing in atomic ensembles enables atom interferometry with sensitivities below the shot-noise limit, but the associated entanglement is highly susceptible to loss, making…
Parameter Estimation from Amplitude Collapse in Correlated Matter-Wave Interference
Daniel Derr, Dominik Pfeiffer, Ludwig Lind +2
Operating matter-wave interferometers as quantum detectors for fundamental physics or inertial sensors with unprecedented accuracies relies on noise rejection, often implemented by…
INTENTAS -- An entanglement-enhanced atomic sensor for microgravity
O. Anton, I. Bröckel, D. Derr +21
The INTENTAS project aims to develop an atomic sensor utilizing entangled Bose-Einstein condensates (BECs) in a microgravity environment. This key achievement is necessary to advan…
Finite-Speed-of-Light Effects in Atom Interferometry: Diffraction Mechanisms and Resonance Conditions
Christian Niehof, Daniel Derr, Enno Giese
Light-pulse atom interferometers serve as tools for high-precision metrology and are targeting measurements of relativistic effects. This development is facilitated by extended int…
