Distribution of genuine high-dimensional entanglement over 10.2 km of noisy metropolitan atmosphere
Lukas Bulla, Kristian Hjorth, Oskar Kohout +9
In a recent quantum key distribution experiment, high-dimensional protocols were used to show an improved noise resistance over a 10.2 km free-space channel. One of the unresolved…
Verifying bound entanglement of dephased Werner states
P. Thomas, M. Bohmann, W. Vogel
The verification of quantum entanglement under the influence of realistic noise and decoherence is crucial for the development of quantum technologies. Unfortunately, a full entang…
Direct calibration of click-counting detectors
Martin Bohmann, Regina Kruse, Jan Sperling +2
We introduce and experimentally implement a method for the absolute detector calibration of photon-number-resolving time-bin multiplexing layouts based on the measured click statis…
Higher-order nonclassical effects in fluctuating-loss channels
M. Bohmann, J. Sperling, A. A. Semenov +1
We study the evolution of higher-order nonclassicality and entanglement criteria in atmospheric fluctuating-loss channels. By formulating input-output relations for the matrix of m…
Entanglement and phase properties of noisy N00N states
M. Bohmann, J. Sperling, W. Vogel
Quantum metrology and quantum information necessitate a profound study of suitable states. Attenuations induced by free-space communication links or fluctuations in the generation…
