Free-Space distribution of entanglement and single photons over 144 km
R. Ursin, F. Tiefenbacher, T. Schmitt-Manderbach +15
Quantum Entanglement is the essence of quantum physics and inspires fundamental questions about the principles of nature. Moreover it is also the basis for emerging technologies of…
Measuring the absolute photo detection efficiency using photon number correlations
Michael Lindenthal, Johannes Kofler
We present two methods for determining the absolute detection efficiency of photon-counting detectors directly from their singles rates under illumination from a nonclassical light…
Distributing entanglement and single photons through an intra-city, free-space quantum channel
K. J. Resch, M. Lindenthal, B. Blauensteiner +11
We have distributed entangled photons directly through the atmosphere to a receiver station 7.8 km away over the city of Vienna, Austria at night. Detection of one photon from our…
