High-fidelity transmission of entanglement over a high-loss freespace channel
Alessandro Fedrizzi, Rupert Ursin, Thomas Herbst +6
Quantum entanglement enables tasks not possible in classical physics. Many quantum communication protocols require the distribution of entangled states between distant parties. Her…
Anti-symmetrization reveals hidden entanglement
Alessandro Fedrizzi, Thomas Herbst, Markus Aspelmeyer +3
Two-photon anti-bunching at a beamsplitter is only possible if the photons are entangled in a specific state, anti-symmetric in the spatial modes. Thus, observation of anti-bunchin…
A wavelength-tunable fiber-coupled source of narrowband entangled photons
Alessandro Fedrizzi, Thomas Herbst, Andreas Poppe +2
We demonstrate a wavelength-tunable, fiber-coupled source of polarization-entangled photons with extremely high spectral brightness and quality of entanglement. Using a 25 mm PPKTP…
