Witnessing trustworthy single-photon entanglement with local homodyne measurements
Olivier Morin, Jean-Daniel Bancal, Melvyn Ho +5
Single-photon entangled states, i.e. states describing two optical paths sharing a single photon, constitute the simplest form of entanglement. Yet they provide a valuable resource…
Bell inequalities for three systems and arbitrarily many measurement outcomes
Basile Grandjean, Yeong-Cherng Liang, Jean-Daniel Bancal +2
We present a family of Bell inequalities for three parties and arbitrarily many outcomes, which can be seen as a natural generalization of the Mermin Bell inequality. For a small n…
Useful multipartite correlations from useless reduced states
Lars Erik Würflinger, Jean-Daniel Bancal, Antonio Acín +2
Understanding what can be inferred about a multi-particle quantum system from only the knowledge of its subparts is a highly non-trivial task. Clearly, if the global system doesn't…
Imperfect measurements settings: implications on quantum state tomography and entanglement witnesses
Denis Rosset, Raphael Ferretti-Schöbitz, Jean-Daniel Bancal +2
Reliable and well-characterized quantum resources are indispensable ingredients in quantum information processing. Typically, in a realistic characterization of these resources, ap…
A framework for the study of symmetric full-correlation Bell-like inequalities
Jean-Daniel Bancal, Cyril Branciard, Nicolas Brunner +2
Full-correlation Bell-like inequalities represent an important subclass of Bell-like inequalities that have found applications in both a better understanding of fundamental physics…
