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…
