Extremal states for photon number and quadratures as gauges for nonclassicality
Z. Hradil, J. Rehacek, P. de la Hoz +2
Rotated quadratures carry the phase-dependent information of the electromagnetic field, so they are somehow conjugate to the photon number. We analyze this noncanonical pair, findi…
Giant Narrowband Twin-Beam Generation along the Pump Energy Propagation
Angela M. Perez, Kirill Yu. Spasibko, Polina R. Sharapova +3
Walk-off effects, originating from the difference between the group and phase velocities, limit the efficiency of nonlinear optical interactions. While transverse walk-off can be e…
Resonant photo-ionization of Yb+ to Yb2+
Simon Heugel, Martin Fischer, Vladimir Elman +3
We demonstrate the controlled creation of a ion by photo-ionizing with weak continuous-wave lasers at ultraviolet wavelengths. The ph…
Temporal and spectral properties of quantum light
Birgit Stiller, Ulrich Seyfarth, Gerd Leuchs
The modes of the electromagnetic field are solutions of Maxwell's equations taking into account the material boundary conditions. The field modes of classical optics - properly nor…
Quantumness of Gaussian Discord: Experimental Evidence and Role of System-Environment Correlations
Vanessa Chille, Niall Quinn, Christian Peuntinger +5
We provide experimental evidence of quantum features in bi-partite states classified as entirely classical according to a conventional criterion based on the Glauber P-function but…
Photon-Atom Coupling with Parabolic Mirrors
Markus Sondermann, Gerd Leuchs
Efficient coupling of light to single atomic systems has gained considerable attention over the past decades. This development is driven by the continuous growth of quantum technol…
