Momentum Entanglement for Atom Interferometry
F. Anders, A. Idel, P. Feldmann +13
Compared to light interferometers, the flux in cold-atom interferometers is low and the associated shot noise large. Sensitivities beyond these limitations require the preparation…
Dynamical low-noise microwave source for cold-atom experiments
Bernd Meyer-Hoppe, Maximilian Baron, Christophe Cassens +4
The generation and manipulation of ultracold atomic ensembles in the quantum regime require the application of dynamically controllable microwave fields with ultra-low noise perfor…
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…
Creation of entangled atomic states by an analogue of the Dynamical Casimir Effect
K. Lange, J. Peise, B. Lücke +7
If the boundary conditions of the quantum vacuum are changed in time, quantum field theory predicts that real, observable particles can be created in the initially empty modes. Her…
Entanglement between two spatially separated atomic modes
Karsten Lange, Jan Peise, Bernd Lücke +6
Modern quantum technologies in the fields of quantum computing, quantum simulation and quantum metrology require the creation and control of large ensembles of entangled particles.…
0.75 atoms improve the clock signal of 10,000 atoms
I. Kruse, K. Lange, J. Peise +8
Since the pioneering work of Ramsey, atom interferometers are employed for precision metrology, in particular to measure time and to realize the second. In a classical interferomet…
Satisfying the Einstein-Podolsky-Rosen criterion with massive particles
J. Peise, I. Kruse, K. Lange +8
In 1935, Einstein, Podolsky and Rosen (EPR) questioned the completeness of quantum mechanics by devising a quantum state of two massive particles with maximally correlated space an…
Interaction-free measurements by quantum Zeno stabilisation of ultracold atoms
J. Peise, B. Lücke, L. Pezzè +6
Quantum mechanics predicts that our physical reality is influenced by events that can potentially happen but factually do not occur. Interaction-free measurements (IFMs) exploit th…
Detecting metrologically useful entanglement in the vicinity of Dicke states
Iagoba Apellaniz, Bernd Lücke, Jan Peise +2
We present a method to verify the metrological usefulness of noisy Dicke states of a particle ensemble with only a few collective measurements, without the need for a direct measur…
Detecting multiparticle entanglement of Dicke states
Bernd Lücke, Jan Peise, Giuseppe Vitagliano +4
Recent experiments demonstrate the production of many thousands of neutral atoms entangled in their spin degrees of freedom. We present a criterion for estimating the amount of ent…
Twin matter waves for interferometry beyond the classical limit
Bernd Lücke, Manuel Scherer, Jens Kruse +10
Interferometers with atomic ensembles constitute an integral part of modern precision metrology. However, these interferometers are fundamentally restricted by the shot noise limit…
Compton Scattering by the Proton using a Large-Acceptance Arrangement
S. Wolf, V. Lisin, R. Kondratiev +24
Compton scattering by the proton has been measured using the tagged-photon facility at MAMI (Mainz) and the large-acceptance arrangement LARA. The new data are interpreted in terms…
Compton Scattering by the Proton
G. Galler, V. Lisin, R. Kondratiev +24
Compton scattering by the proton has been measured over a wide range covering photon energies 250 MeV < E_γ< 800 MeV and photon scattering angles 30^0 < θ^{lab}_γ< 150^0, using the…
