Faking entanglement with imperceptible measurement deviations
Jaime Moreno, Elna Svegborn, Simon Morelli +4
Quantum entanglement is a central resource underpinning emerging quantum technologies, enabling capabilities beyond those of classical systems. Accurate verification of entanglemen…
Conservation of angular momentum on a single-photon level
Lea Kopf, Rafael Barros, Shashi Prabhakar +2
Identifying conservation laws is central to every subfield of physics, as they illuminate the underlying symmetries and fundamental principles. A prime example can be found in quan…
Higher-order Poincaré Spheres and Spatio-Spectral Poincaré Beams
Robert Fickler, Lea Kopf, Marco Ornigotti
The study of fundamental optics effects has been stimulated through the increasing ability to structure light in all its degrees of freedom (DOFs) in sophisticated but simple exper…
Correlating space, wavelength, and polarization of light: Spatio-Spectral Vector Beams
Lea Kopf, Rafael Barros, Robert Fickler
Increasing the complexity of a light field through the advanced manipulation of its degrees of freedom (DoF) provides new opportunities for fundamental studies and technologies. Co…
Talbot self-imaging and two-photon interference in ring-core fibers
Matias Eriksson, Benjamin A. Stickler, Lea Kopf +5
Wave propagation on the surface of cylinders exhibits interferometric self imaging, much like the Talbot effect in the near-field diffraction at periodic gratings. We report the ex…
Endless Fun in high dimensions -- A Quantum Card Game
Lea Kopf, Markus Hiekkamäki, Shashi Prabhakar +1
Quantum technologies, i.e., technologies benefiting from the features of quantum physics such as objective randomness, superposition, and entanglement, have enabled an entirely dif…
Spectral Vector Beams for High-Speed Spectroscopic Measurements
Lea Kopf, Juan R. Deop Ruano, Markus Hiekkamäki +4
Structured light harnessing multiple degrees of freedom has become a powerful approach to use complex states of light in fundamental studies and applications. Here, we investigate…
