Spin squeezing of atomic ensembles by multi-colour quantum non-demolition measurements
M. Saffman, D. Oblak, J. Appel +1
We analyze the creation of spin squeezed atomic ensembles by simultaneous dispersive interactions with several optical frequencies. A judicious choice of optical parameters enables…
Echo Spectroscopy of Atomic Dynamics in a Gaussian Trap via Phase Imprints
Daniel Oblak, Juergen Appel, Patrick Windpassinger +3
We report on the collapse and revival of Ramsey fringe visibility when a spatially dependent phase is imprinted in the coherences of a trapped ensemble of two-level atoms. The phas…
Loading of large ion Coulomb crystals into a linear Paul trap incorporating an optical cavity for cavity QED studies
P. Herskind, A. Dantan, M. B. Langkilde-Lauesen +3
We report on the loading of large ion Coulomb crystals into a linear Paul trap incorporating a high-Finesse optical cavity (F~3200). We show that, even though the 3-mm diameter die…
Establishing EPR-channels between Nanomechanics and Atomic Ensembles
K. Hammerer, M. Aspelmeyer, E. S. Polzik +1
We suggest to interface nanomechanical systems via an optical quantum bus to atomic ensembles, for which means of high precision state preparation, manipulation and measurement are…
Spin squeezing of atomic ensembles via nuclear-electronic spin entanglement
T. Fernholz, H. Krauter, K. Jensen +3
Entangled many body systems have recently attracted significant attention in various contexts. Among them, spin squeezed atoms and ions have raised interest in the field of precisi…
