Fermions are fundamentally more nonlocal than Bosons
Fatemeh Moradi Kalarde, Sadra Boreiri, Xiangling Xu +5
Bell's theorem shows that entangled quantum particles can exhibit correlations that classical particles cannot reproduce without an additional nonlocal resource, such as communicat…
Stronger Welch Bounds and Optimal Approximate -Designs
Riccardo Castellano, Dmitry Grinko, Sadra Boreiri +2
A fundamental question asks how uniformly finite sets of pure quantum states can be distributed in a Hilbert space. The Welch bounds address this question, and are saturated by …
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…
Bell nonlocality in quantum networks with unreliable sources: Loophole-free postelection via self-testing
Sadra Boreiri, Nicolas Brunner, Pavel Sekatski
We discuss Bell nonlocality in quantum networks with unreliable sources. Our main result is a condition on the observed data which ensures that inconclusive events can be safely di…
Topologically Robust Quantum Network Nonlocality
Sadra Boreiri, Tamas Krivachy, Pavel Sekatski +2
We discuss quantum network Bell nonlocality in a setting where the network structure is not fully known. More concretely, an honest user may trust their local network topology, but…
