Cyclic transformation of orbital angular momentum modes
Florian Schlederer, Mario Krenn, Robert Fickler +2
The spatial modes of photons are one realization of a QuDit, a quantum system that is described in a D-dimensional Hilbert space. In order to perform quantum information tasks with…
Quantifying high dimensional entanglement with two mutually unbiased bases
Paul Erker, Mario Krenn, Marcus Huber
We derive a framework for quantifying entanglement in multipartite and high dimensional systems using only correlations in two unbiased bases. We furthermore develop such bounds in…
On Small Beams with Large Topological Charge
Mario Krenn, Nora Tischler, Anton Zeilinger
Light beams can carry a discrete, in principle unbounded amount of angular momentum. Examples of such beams, the Laguerre-Gauss modes, are frequently expressed as solutions of the…
Physical meaning of the radial index of Laguerre-Gauss beams
William N. Plick, Mario Krenn
The Laguerre-Gauss modes are a class of fundamental and well-studied optical fields. These stable, shape-invariant photons - exhibiting circular-cylindrical symmetry - are familiar…
Multi-photon entanglement in high dimensions
Mehul Malik, Manuel Erhard, Marcus Huber +3
Entanglement lies at the heart of quantum mechanics as a fundamental tool for testing its deep rift with classical physics, while also providing a key resource for quantum tech…
Automated Search for new Quantum Experiments
Mario Krenn, Mehul Malik, Robert Fickler +2
Quantum mechanics predicts a number of at first sight counterintuitive phenomena. It is therefore a question whether our intuition is the best way to find new experiments. Here we…
