Robert Fickler: Quantum experiments with twisted photons
Robert Fickler, University of Vienna
The transverse spatial degree of freedom of light offers great potential to explore quantum informational tasks and interesting features of single photons and quantum entanglement. We developed novel methods to generate, investigate, and verify the entanglement of complex spatial structures. With these methods, we were able to entangle photons with up to 300 quanta of orbital angular momentum (OAM) and to image the effect of entanglement of twisted photons in real-time.
