More Randomness from the Same Data
Jean-Daniel Bancal, Lana Sheridan, Valerio Scarani
Correlations that cannot be reproduced with local variables certify the generation of private randomness. Usually, the violation of a Bell inequality is used to quantify the amount…
Device-independent certification of the teleportation of a qubit
Melvyn Ho, Jean-Daniel Bancal, Valerio Scarani
We want to certify in a black box scenario that two parties simulating the teleportation of a qubit are really using quantum resources. If active compensation is part of the simula…
Physical characterization of quantum devices from nonlocal correlations
Jean-Daniel Bancal, Miguel Navascués, Valerio Scarani +2
In the device-independent approach to quantum information theory, quantum systems are regarded as black boxes which, given an input (the measurement setting), return an output (the…
Strong constraints on models that explain the violation of Bell inequalities with hidden superluminal influences
Valerio Scarani, Jean-Daniel Bancal, Antoine Suarez +1
We discuss models that attempt to provide an explanation for the violation of Bell inequalities at a distance in terms of hidden influences. These models reproduce the quantum corr…
Tripartite quantum state violating the hidden influence constraints
Tomer Jack Barnea, Jean-Daniel Bancal, Yeong-Cherng Liang +1
The possibility to explain quantum correlations via (possibly) unknown causal influences propagating gradually and continuously at a finite speed v > c has attracted a lot of atten…
Device-independent demonstration of genuine multipartite entanglement
Julio T. Barreiro, Jean-Daniel Bancal, Philipp Schindler +5
Entanglement in a quantum system can be demonstrated experimentally by performing the measurements prescribed by an appropriate entanglement witness. However, the unavoidable misma…
