Symmetric observations without symmetric causal explanations
Christian William, Patrick Remy, Jean-Daniel Bancal +3
Inferring causal models from observed correlations is a challenging task, crucial to many areas of science. In order to alleviate the computational effort when sifting through poss…
Automated generation of photonic circuits for Bell tests with homodyne measurements
Corentin Lanore, Federico Grasselli, Xavier Valcarce +2
Nonlocal quantum realizations, certified by the violation of a Bell inequality, are core resources for device-independent quantum information processing. Although proof-of-principl…
Towards Device-Independent Quantum Key Distribution with Photonic Devices
Corentin Lanore, Xavier Valcarce, Jean Etesse +2
Quantum Key Distribution (QKD) protocols enable two distant parties to communicate with information-theoretically proven secrecy. However, these protocols are generally vulnerable…
Testing the Wineland Criterion with Finite Statistics
E. S. Carrera, Y. Zhang, J-D. Bancal +1
The Wineland parameter aims at detecting metrologically useful entangled states, called spin-squeezed states, from expectations and variances of total angular momenta. {However, ef…
