Mesoscopic atomic entanglement for precision measurements beyond the standard quantum limit
J. Appel, P. J. Windpassinger, D. Oblak +3
Squeezing of quantum fluctuations by means of entanglement is a well recognized goal in the field of quantum information science and precision measurements. In particular, squeezin…
Quantum interface between light and atomic ensembles
K. Hammerer, A. S. Sorensen, E. S. Polzik
During the past decade the interaction of light with multi-atom ensembles has attracted a lot of attention as a basic building block for quantum information processing and quantum…
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…
