Atmospheric continuous-variable quantum communication
Bettina Heim, Christian Peuntinger, Nathan Killoran +4
We present a quantum communication experiment conducted over a point-to-point free-space link of 1.6 km in urban conditions. We study atmospheric influences on the capability of th…
The polarization properties of a tilted polarizer
Jan Korger, Tobias Kolb, Peter Banzer +4
Polarizers are key components in optical science and technology. Thus, understanding the action of a polarizer beyond oversimplifying approximations is crucial. In this work, we st…
Observation of the geometric spin Hall effect of light
Jan Korger, Andrea Aiello, Vanessa Chille +5
The spin Hall effect of light (SHEL) is the photonic analogue of spin Hall effects occurring for charge carriers in solid-state systems. Typical examples of this intriguing phenome…
Optimal working points for continuous-variable quantum channels
Imran Khan, Christoffer Wittmann, Nitin Jain +4
The most important ability of a quantum channel is to preserve the quantum properties of transmitted quantum states. We experimentally demonstrate a continuous-variable system for…
Entanglement of Gaussian states and the applicability to quantum key distribution over fading channels
Vladyslav C. Usenko, Bettina Heim, Christian Peuntinger +4
Entanglement properties of Gaussian states of light as well as the security of continuous variable quantum key distribution with Gaussian states in free-space fading channels are s…
A Versatile Source of Single Photons for Quantum Information Processing
Michael Förtsch, Josef Fürst, Christoffer Wittmann +6
The quantum state of a single photon stands among the most fundamental and intriguing manifestations of quantum physics. At the same time single photons and pairs of single photons…
