Simultaneous transmission of hyper-entanglement in 3 degrees of freedom through a multicore fiber
Lukas Achatz, Lukas Bulla, Evelyn A. Ortega +5
Entanglement distribution is at the heart of most quantum communication protocols. Inevitable loss of photons along quantum channels is a major obstacle for distributing entangled…
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…
Non-local temporal interferometry for highly resilient free-space quantum communication
Lukas Bulla, Matej Pivoluska, Kristian Hjorth +9
Entanglement distribution via photons over long distances enables many applications, including quantum key distribution (QKD), which provides unprecedented privacy. The inevitable…
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…
Advances in entanglement-based QKD for space applications
Sebastian Ecker, Johannes Pseiner, Jorge Piris +1
Quantum key distribution (QKD) enables tap-proof exchange of cryptographic keys guaranteed by the very laws of physics. One of the last remaining roadblocks on the way towards wide…
Distribution of genuine high-dimensional entanglement over 10.2 km of noisy metropolitan atmosphere
Lukas Bulla, Kristian Hjorth, Oskar Kohout +9
In a recent quantum key distribution experiment, high-dimensional protocols were used to show an improved noise resistance over a 10.2 km free-space channel. One of the unresolved…
