Quantum Entanglement of High Angular Momenta
Robert Fickler,Robert Fickler,Radek Lapkiewicz,Radek Lapkiewicz,William N. Plick,William N. Plick,Mario Krenn,Mario Krenn,Christoph Schaeff,Christoph Schaeff,Sven Ramelow,Sven Ramelow,Anton Zeilinger,Anton Zeilinger +13 more
TL;DR: A method for converting the polarization state of photons into information encoded into spatial modes of a single photon is presented and entanglement of very high OAM can improve the sensitivity of angular resolution in remote sensing.
Journal ArticleDOI
Twisted photons: new quantum perspectives in high dimensions
TL;DR: In this paper, a review of the theoretical differences between qubits and higher dimensional systems, qudits, in different quantum information scenarios is given. And the authors consider the advantages of such higher-dimensional systems, which include higher information capacity and greater protection from eavesdropping.
Journal ArticleDOI
Communication with spatially modulated light through turbulent air across Vienna

TL;DR: In this article, the authors used an artificial neural network (ANN) to identify the characteristic mode patterns displayed on a screen at the receiver, and were able to distinguish between 16 different OAM superposition with only a 1.7% error rate.
Journal ArticleDOI
Generation and confirmation of a (100 × 100)-dimensional entangled quantum system
Mario Krenn,Mario Krenn,Marcus Huber,Marcus Huber,Robert Fickler,Robert Fickler,Radek Lapkiewicz,Radek Lapkiewicz,Sven Ramelow,Sven Ramelow,Anton Zeilinger,Anton Zeilinger +11 more
TL;DR: A novel nonlinear criterion is developed which infers entanglement dimensionality of a global state by using only information about its subspace correlations, which allows very practical experimental implementation as well as highly efficient extraction of entanglements dimensionality information.

TL;DR: The transmission of orbital angular momentum modes of light over a distance of 143 km between two Canary Islands is shown, indicating that with state-of-the-art adaptive optics systems, both classical communication and entanglement transmission is feasible over distances of more than 100 km.
