A Highly Nondegenerate Photon-Pair Source for Detector-Matched Quantum Key Distribution
Sander van Haagen, Bora Ulu, Alper Ozulker +4
In a commercial entanglement-distribution system over telecom fibre, the single-photon detectors are the largest part of the hardware cost. In entanglement-based quantum key distri…
Multi-copy and Catalytic Superactivation of Genuine Multipartite Nonlocality
Bora Ulu, Mirjam Weilenmann, Nicolas Brunner
Genuine multipartite Bell nonlocality (GMNL) aims at capturing correlations between many distant observers that are globally Bell nonlocal. A commonly used definition for GMNL is b…
Device Independent Quantum Key Activation
Bora Ulu, Nicolas Brunner, Mirjam Weilenmann
Device-independent quantum key distribution (DIQKD) allows two distant parties to establish a secret key, based only on the observed Bell nonlocal distribution. It remains however,…
Noise-robust proofs of quantum network nonlocality
Sadra Boreiri, Bora Ulu, Nicolas Brunner +1
Quantum networks allow for novel forms of quantum nonlocality. By exploiting the combination of entangled states and entangled measurements, strong nonlocal correlations can be gen…
Towards a minimal example of quantum nonlocality without inputs
Sadra Boreiri, Antoine Girardin, Bora Ulu +3
The network scenario offers interesting new perspectives on the phenomenon of quantum nonlocality. Notably, when considering networks with independent sources, it is possible to de…
