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…
All-fibre source of amplitude-squeezed light pulses
Markus Meissner, Christoph Marquardt, Joel Heersink +4
An all-fibre source of amplitude squeezed solitons utilizing the self-phase modulation in an asymmetric Sagnac interferometer is experimentally demonstrated. The asymmetry of the i…
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…
Continuous variable quantum key distribution using polarization encoding and post selection
Stefan Lorenz, Natalia Korolkova, Gerd Leuchs
We present an experimental demonstration of a quantum key distribution protocol using coherent polarization states. Post selection is used to ensure a low error rate and security a…
