Efficient saturation of an ion in free space
Martin Fischer, Marianne Bader, Robert Maiwald +3
We report on the demonstration of a light-matter interface coupling light to a single ion in free space. The interface is realized through a parabolic mirror…
Interference of macroscopic beams on a beam splitter: phase uncertainty converted into photon-number uncertainty
K. Yu. Spasibko, F. Töppel, T. Sh. Iskhakov +3
Squeezed-vacuum twin beams, commonly generated through parametric down-conversion, are known to have perfect photon-number correlations. According to the Heisenberg principle, this…
Scattering of an exponential pulse by a single atom
Markus Sondermann, Gerd Leuchs
We discuss the scattering of a light pulse by a single atom in free space using a purely semi-classical framework. The atom is treated as a linear elastic scatterer allowing to tre…
The phase shift induced by a single atom in free space
Markus Sondermann, Gerd Leuchs
In this article we theoretically study the phase shift a single atom imprints onto a coherent state light beam in free space. The calculations are performed in a semiclassical fram…
QED with a parabolic mirror
G. Alber, J. Z. Bernád, M. Stobińska +2
We investigate the quantum electrodynamics of a single two-level atom located at the focus of a parabolic cavity. We first work out the modifications of the spontaneous emission in…
Distributing Entanglement with Separable States
Christian Peuntinger, Vanessa Chille, Ladislav Mišta +5
Like a silver thread, quantum entanglement [1] runs through the foundations and breakthrough applications of quantum information theory. It cannot arise from local operations and c…
