Witnessing effective entanglement in a continuous variable prepare&measure setup and application to a QKD scheme using postselection
S. Lorenz, J. Rigas, M. Heid +3
We report an experimental demonstration of effective entanglement in a prepare&measure type of quantum key distribution protocol. Coherent polarization states and heterodyne measur…
Experimental distillation of squeezing from non-Gaussian quantum states
J. Heersink, Ch. Marquardt, R. Dong +4
We show theoretically and experimentally that single copy distillation of squeezing from continuous variable non-Gaussian states is possible using linear optics and conditional hom…
Reduction of Guided Acoustic Wave Brillouin Scattering in Photonic Crystal Fibers
D. Elser, U. L. Andersen, A. Korn +4
Guided Acoustic Wave Brillouin Scattering (GAWBS) generates phase and polarization noise of light propagating in glass fibers. This excess noise affects the performance of various…
Demonstration of the spatial separation of the entangled quantum side-bands of an optical field
E. H. Huntington, G. N. Milford, C. Robilliard +5
Quantum optics experiments on "bright" beams typically probe correlations between side-band modes. However the extra degree of freedom represented by this dual mode picture is gene…
Experimental demonstration of continuous variable quantum erasing
Ulrik L. Andersen, Oliver Glöckl, Stefan Lorenz +2
We experimentally demonstrate the concept of continuous variable quantum erasing. The amplitude quadrature of the signal state is labelled to another state via a quantum nondemolit…
Sub shot noise phase quadrature measurement of intense light beams
O. Glöckl, U. L. Andersen, S. Lorenz +3
We present a setup to perform sub shot noise measurements of the phase quadrature for intense pulsed light without the use of a separate local oscillator. A Mach--Zehnder interfero…
