Experimental demonstration of quantum correlations over more than 10 km
W. Tittel, J. Brendel, B. Gisin +3
Energy and time entangled photons at a wavelength of 1310 nm are produced by parametric downconversion in a KNbO3 crystal and are sent into all-fiber interferometers using a teleco…

Non-local two-photon correlations using interferometers physically separated by 35 meters
W. Tittel, J. Brendel, T. Herzog +2
An experimental demonstration of quantum correlations is presented. Energy and time entangled photons at wavelengths of 704 and 1310 nm are produced by parametric downconversion in…

``Plug and play'' systems for quantum cryptography
A. Muller, T. Herzog, B. Huttner +3
We present a time-multiplexed interferometer based on Faraday mirrors, and apply it to quantum key distribution. The interfering pulses follow exactly the same spatial path, ensuri…
