State independent QKD
Robert Kindler, Johannes Handsteiner, Jaroslav Kysela +3
We present an adaptive procedure for aligning quantum non-locality experiments without any knowledge of the two-qudit state shared by the participating parties. The quantum state p…
Fully passive entanglement based quantum key distribution scheme
Bo Liu, Matej Pivoluska, Johannes Handsteiner +5
In general, generation of entangled photon pairs and also the random choice of measurement basis can be implemented with passive optical devices in entanglement based quantum key d…
Strategies for achieving high key rates in satellite-based QKD
Sebastian Ecker, Bo Liu, Johannes Handsteiner +6
Quantum key distribution (QKD) is a pioneering quantum technology on the brink of widespread deployment. Nevertheless, the distribution of secret keys beyond a few 100 kilometers a…
Entanglement-enhanced optical gyroscope
Matthias Fink, Fabian Steinlechner, Johannes Handsteiner +3
Fiber optic gyroscopes (FOG) based on the Sagnac effect are a valuable tool in sensing and navigation and enable accurate measurements in applications ranging from spacecraft and a…
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…
Challenging local realism with human choices
The BIG Bell Test Collaboration, C. Abellán, A. Acín +105
A Bell test is a randomized trial that compares experimental observations against the philosophical worldview of local realism. A Bell test requires spatially distributed entanglem…
Satellite-relayed intercontinental quantum network
Sheng-Kai Liao, Wen-Qi Cai, Johannes Handsteiner +33
We perform decoy-state quantum key distribution between a low-Earth-orbit satellite and multiple ground stations located in Xinglong, Nanshan, and Graz, which establish satellite-t…
Cosmic Bell Test: Measurement Settings from Milky Way Stars
Johannes Handsteiner, Andrew S. Friedman, Dominik Rauch +17
Bell's theorem states that some predictions of quantum mechanics cannot be reproduced by a local-realist theory. That conflict is expressed by Bell's inequality, which is usually d…
Experimental test of photonic entanglement in accelerated reference frames
Matthias Fink, Ana Rodriguez-Aramendia, Johannes Handsteiner +7
The quantization of the electromagnetic field has successfully paved the way for the development of the Standard Model of Particle Physics and has established the basis for quantum…
Twisted Light Transmission over 143 kilometers
Mario Krenn, Johannes Handsteiner, Matthias Fink +4
Spatial modes of light can potentially carry a vast amount of information, making them promising candidates for both classical and quantum communication. However, the distribution…
Significant-loophole-free test of Bell's theorem with entangled photons
Marissa Giustina, Marijn A. M. Versteegh, Sören Wengerowsky +19
Local realism is the worldview in which physical properties of objects exist independently of measurement and where physical influences cannot travel faster than the speed of light…
Twisted photon entanglement through turbulent air across Vienna
Mario Krenn, Johannes Handsteiner, Matthias Fink +2
Photons with a twisted phase front can carry a discrete, in principle unbounded amount of orbital angular momentum (OAM). The large state space allows for complex types of entangle…
Teleportation of entanglement over 143 km
Thomas Herbst, Thomas Scheidl, Matthias Fink +4
As a direct consequence of the no-cloning theorem, the deterministic amplification as in classical communication is impossible for quantum states. This calls for more advanced tech…
Communication with spatially modulated Light through turbulent Air across Vienna
Mario Krenn, Robert Fickler, Matthias Fink +5
The transverse spatial modes of light offer a large state-space with interesting physical properties. For exploiting it in future long-distance experiments, spatial modes will have…
