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…

A Novel Protocol-Authentication Algorithm Ruling Out a Man-in-the-Middle Attack in Quantum Cryptography
M. Peev, M. Nölle, O. Maurhardt +6
In this work we review the security vulnerability of Quantum Cryptography with respect to "man-in-the-middle attacks" and the standard authentication methods applied to counteract…
