Entangling single atoms over 33 km telecom fibre
Tim van Leent, Matthias Bock, Florian Fertig +10
Heralded entanglement between distant quantum memories is the key resource for quantum networks. Based on quantum repeater protocols, these networks will facilitate efficient large…
Experimental device-independent quantum key distribution between distant users
Wei Zhang, Tim van Leent, Kai Redeker +7
Device-independent quantum key distribution (DIQKD) is the art of using untrusted devices to establish secret keys over an untrusted channel. So far, the real-world implementation…
Certified Randomness from Remote State Preparation Dimension Witness
Xing Chen, Kai Redeker, Robert Garthoff +3
Randomness in Bell test data can be device-independently certified by Bell's theorem without placing assumptions about the experimental devices. The device-independent randomness h…
Long-distance distribution of atom-photon entanglement at telecom wavelength
Tim van Leent, Matthias Bock, Robert Garthoff +6
Entanglement between stationary quantum memories and photonic channels is the essential resource for future quantum networks. Together with entanglement distillation it will enable…
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…
Event-Ready Bell Test Using Entangled Atoms Simultaneously Closing Detection and Locality Loopholes
Wenjamin Rosenfeld, Daniel Burchardt, Robert Garthoff +4
An experimental test of Bell's inequality allows ruling out any local-realistic description of nature by measuring correlations between distant systems. While such tests are concep…
Generalized Spatial and Spatiotemporal Autoregressive Conditional Heteroscedasticity
Philipp Otto, Wolfgang Schmid, Robert Garthoff
In this paper, we introduce a new spatial model that incorporates heteroscedastic variance depending on neighboring locations. The proposed process is regarded as the spatial equiv…
