Squeezed state purification with linear optics and feed forward
O. Glöckl, U. L. Andersen, R. Filip +2
A scheme for optimal and deterministic linear optical purification of mixed squeezed Gaussian states is proposed and experimentally demonstrated. The scheme requires only linear op…
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…
Verifying continuous variable entanglement of intense light pulses
O. Glöckl, U. L. Andersen, G. Leuchs
Three different methods have been discussed to verify continuous variable entanglement of intense light beams. We demonstrate all three methods using the same set--up to facilitate…
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…
