Catalytic Activation of Bell Nonlocality
Jessica Bavaresco, Nicolas Brunner, Antoine Girardin +2
The correlations of certain entangled states can be perfectly simulated classically via a local model. Hence such states are termed Bell local, as they cannot lead to Bell inequali…
All Entangled States are Nonlocal and Self-Testable in the Broadcast Scenario
Pavel Sekatski, Jef Pauwels
Entanglement and Bell nonlocality are known to be inequivalent: there exist entangled states that admit a local hidden-variable model for all local measurements. Here we show that…
Partial independence suffices to rule out Real Quantum Theory experimentally
Mirjam Weilenmann, Nicolas Gisin, Pavel Sekatski
The role of complex quantities in quantum theory has been puzzling physicists since the beginnings. It is thus natural to ask whether, in order to describe our experiments, the mat…
The power of quantum catalytic local operations
Patryk Lipka-Bartosik, Jessica Bavaresco, Nicolas Brunner +1
A key result in entanglement theory is that the addition of a catalyst dramatically enlarges the set of possible state transformations via local operations and classical communicat…
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…
Certification of quantum correlations and DIQKD at arbitrary distances through routed Bell tests
Pavel Sekatski, Jef Pauwels, Edwin Peter Lobo +2
Transmission loss represents a major obstacle to the device-independent certification of quantum correlations over long distances, limiting applications such as device-independent…
