Classical entanglement: Oxymoron or resource?
Andrea Aiello, Falk Töppel, Christoph Marquardt +2
In this work we review and further develop the controversial concept of "classical entanglement" in optical beams. We present a unified theory for different kinds of light beams ex…
Classical entanglement in polarization metrology
Falk Töppel, Andrea Aiello, Christoph Marquardt +2
Quantum approaches relying on entangled photons have been recently proposed to increase the efficiency of optical measurements. We demonstrate here that, surprisingly, the use of c…
Goos-Hänchen and Imbert-Fedorov shifts from a quantum-mechanical perspective
Falk Töppel, Marco Ornigotti, Andrea Aiello
We study the classical optics effects known as Goos-Hänchen (GH) and Imbert-Fedorov (IF) shifts, occurring when reflecting a bounded light beam from a planar surface, by using a qu…
Towards loophole-free Bell inequality test with preselected unsymmetrical singlet states of light
M. Stobińska, F. Töppel, P. Sekatski +1
Can a Bell test with no detection loophole be demonstrated for multi-photon entangled states of light within the current technology? We examine the possibility of a postselection-f…
Identical classical particles: half fermions and half bosons
Falk Töppel, Andrea Aiello
We study the problem of particle indistinguishability for the three cases known in nature: identical classical particles, identical bosons and identical fermions. By exploiting the…
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…
Filtering of the absolute value of photon-number difference for two-mode macroscopic quantum superpositions
Magdalena Stobińska, Falk Töppel, Pavel Sekatski +5
We discuss a device capable of filtering out two-mode states of light with mode populations differing by more than a certain threshold, while not revealing which mode is more popul…
