Time correlations in atmospheric quantum channels
M. Klen, D. Vasylyev, W. Vogel +1
Efficient transfer of quantum information between remote parties is a crucial challenge for quantum communication over atmospheric channels. Random fluctuations of the channel tran…
Bell nonlocality in the turbulent atmosphere
M. O. Gumberidze, A. A. Semenov, D. Vasylyev +1
Violations of Bell inequalities are better preserved by turbulent atmospheric channels than by comparable optical fibers in the scenario of copropagating entangled photons [A.A. Se…
Atmospheric Quantum Channels with Weak and Strong Turbulence
D. Vasylyev, A. A. Semenov, W. Vogel
The free-space transfer of high-fidelity optical signals between remote locations has many applications, including both classical and quantum communication, precision navigation, c…
Gaussian entanglement in the turbulent atmosphere
M. Bohmann, A. A. Semenov, J. Sperling +1
We provide a rigorous treatment of the entanglement properties of two-mode Gaussian states in atmospheric channels by deriving and analyzing the input-output relations for the corr…
Homodyne detection for atmosphere channels
A. A. Semenov, F. Töppel, D. Yu. Vasylyev +2
We give a systematic theoretical description of homodyne detection in the case where both the signal and the local oscillator pass through the turbulent atmosphere. Imperfect knowl…
Toward Global Quantum Communication: Beam Wandering Preserves Nonclassicality
D. Yu. Vasylyev, A. A. Semenov, W. Vogel
Tap-proof long-distance quantum communication requires a deep understanding of the strong losses in transmission channels. Here we provide a rigorous treatment of the effects of be…
Fake violations of the quantum Bell-parameter bound
A. A. Semenov, W. Vogel
Shortcomings of experimental techniques are usually assumed to diminish nonclassical properties of quantum systems. Here it is demonstrated that this standard assumption is not tru…
Entanglement transfer through the turbulent atmosphere
A. A. Semenov, W. Vogel
The propagation of polarization-entangled states of light through fluctuating loss channels in the turbulent atmosphere is studied, including the situation of strong losses. We con…
