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…
Bell violation with entangled photons, free of the coincidence-time loophole
Jan-Åke Larsson, Marissa Giustina, Johannes Kofler +3
In a local realist world view, physical properties are defined prior to and independent of measurement, and no physical influence can propagate faster than the speed of light. Prop…
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…
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"…
Phase-stable source of polarization-entangled photons in a linear double-pass configuration
Fabian Steinlechner, Sven Ramelow, Marc Jofre +5
We demonstrate a compact, robust, and highly efficient source of polarization-entangled photons, based on linear bi-directional down-conversion in a novel 'folded sandwich' configu…
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 -…
Bell violation with entangled photons, free of the fair-sampling assumption
Marissa Giustina, Alexandra Mech, Sven Ramelow +9
The violation of a Bell inequality is an experimental observation that forces one to abandon a local realistic worldview, namely, one in which physical properties are (probabilisti…
