Quantum Entanglement of Complex Photon Polarization Patterns in Vector Beams
Robert Fickler, Radek Lapkiewicz, Sven Ramelow +1
We report the efficient creation and detection of hybrid entanglement between one photon's polarization and another photon's complex transverse polarization pattern. The polarizati…
The Forgotten Quantum Number: A short note on the radial modes of Laguerre-Gauss beams
William N. Plick, Radek Lapkiewicz, Sven Ramelow +1
The orbital angular momentum quantum number of Laguerre-Gauss beams has received an explosively increasing amount of attention over the past twenty years. However, often overlooked…
An explicit contextualized hidden variable model replicating an indivisible quantum system
William N. Plick, Radek Lapkiewicz
Recent experiments and theory have further illuminated the concept of "quantum contextuality". In this paper we take an inequality - the Pentagram (or KCBS) inequality, which is vi…
Generation and Confirmation of a (100x100)-dimensional entangled Quantum System
Mario Krenn, Marcus Huber, Robert Fickler +3
Entangled quantum systems have properties that have fundamentally overthrown the classical worldview. Increasing the complexity of entangled states by expanding their dimensionalit…
Comment on "Two Fundamental Experimental Tests of Nonclassicality with Qutrits"
Radek Lapkiewicz, Peizhe Li, Christoph Schaeff +4
In a recent paper [arXiv:1301.2887] Ahrens et al. claim that our "(...) experiment on qutrits does not test Klyachko et al.'s inequality, but an inequality with extra correlations"…
Violation of a new Wigner inequality with high angular momenta
William N. Plick, Robert Fickler, Radek Lapkiewicz +1
In the study of systems that cannot be described classically, the Wigner inequality, has received only a small amount of attention. In this paper we extend the Wigner inequality -…
