Real-Time Imaging of Quantum Entanglement
Robert Fickler, Mario Krenn, Radek Lapkiewicz +2
Quantum Entanglement is widely regarded as one of the most prominent features of quantum mechanics and quantum information science. Although, photonic entanglement is routinely stu…
Direct characterization of linear-optical networks
Saleh Rahimi-Keshari, Matthew A. Broome, Robert Fickler +3
We introduce an efficient method for fully characterizing multimode linear-optical networks. Our approach requires only a standard laser source and intensity measurements to direct…
Quantum orbital angular momentum of elliptically-symmetric light
William N. Plick, Mario Krenn, Robert Fickler +2
We present a quantum mechanical analysis of the orbital angular momentum of a class of recently discovered elliptically-symmetric stable light fields --- the so-called Ince-Gauss m…
Quantum Entanglement of High Angular Momenta
Robert Fickler, Radek Lapkiewicz, William N. Plick +4
Single photons with helical phase structures may carry a quantized amount of orbital angular momentum (OAM) and their entanglement is important for quantum information science and…
Entangled Singularity patterns of Photons in Ince-Gauss modes
Mario Krenn, Robert Fickler, Marcus Huber +4
Photons with complex spatial mode structures open up possibilities for new fundamental high-dimensional quantum experiments and for novel quantum information tasks. Here we show fo…
Scalable fiber integrated source for higher-dimensional path-entangled photonic quNits
Christoph Schaeff, Robert Polster, Radek Lapkiewicz +3
Integrated photonic circuits offer the possibility for complex quantum optical experiments in higher-dimensional photonic systems. However, the advantages of integration and scalab…
