Experimental Single-Copy Entanglement Distillation
Sebastian Ecker, Philipp Sohr, Lukas Bulla +3
The phenomenon of quantum entanglement marks one of the furthest departures from classical physics and is indispensable for quantum information processing. Despite its fundamental…
Overcoming Noise in Entanglement Distribution
Sebastian Ecker, Frédéric Bouchard, Lukas Bulla +8
Noise can be considered the natural enemy of quantum information. An often implied benefit of high-dimensional entanglement is its increased resilience to noise. However, manifesti…
Cosmic Bell Test using Random Measurement Settings from High-Redshift Quasars
Dominik Rauch, Johannes Handsteiner, Armin Hochrainer +17
In this Letter, we present a cosmic Bell experiment with polarization-entangled photons, in which measurement settings were determined based on real-time measurements of the wavele…
Polarization entanglement by time-reversed Hong-Ou-Mandel interference
Yuanyuan Chen, Sebastian Ecker, Sören Wengerowsky +4
Sources of entanglement are an enabling resource in quantum technology, and pushing the limits of generation rate and quality of entanglement is a necessary pre-requisite towards p…
