High-fidelity transmission of polarization encoded qubits from an entangled source over 100 km of fiber
Hannes Hübel, Michael R. Vanner, Thomas Lederer +4
We demonstrate non-degenerate down-conversion at 810 and 1550 nm for long-distance fiber based quantum communication using polarization entangled photon pairs. Measurements of the…

On the optimality of individual entangling-probe attacks against BB84 quantum key distribution
I. Herbauts, S. Bettelli, H. Hübel +1
It is shown that an existing method to study ideal individual attacks on the BB84 QKD protocol using error discard can be adapted to reconciliation with error correction, and that…
