Local contextuality-based self-tests are sufficient for randomness expansion secure against quantum adversaries
Jaskaran Singh, Cameron Foreman, Kishor Bharti +1
In quantum cryptography, secure randomness expansion involves using a short private string of random bits to generate a longer one, even in the presence of an adversary who may hav…
Lifting noncontextuality inequalities
Raman Choudhary, Rui Soares Barbosa, Adán Cabello
Kochen-Specker contextuality is a fundamental feature of quantum mechanics and a crucial resource for quantum computational advantage and reduction of communication complexity. Its…
Loophole-free Bell tests with randomly chosen subsets of measurement settings
Jaskaran Singh, Adán Cabello
There are bipartite quantum nonlocal correlations requiring very low detection efficiency to reach the loophole-free regime but that need too many measurement settings to be practi…
Bell scenarios in which nonlocality and entanglement are inversely related
G. Vallone, G. Lima, E. S. Gómez +4
We show that for two-qubit chained Bell inequalities with an arbitrary number of measurement settings, nonlocality and entanglement are not only different properties but are invers…
Bell Experiments with Random Destination Sources
F. Sciarrino, G. Vallone, A. Cabello +1
It is generally assumed that sources sending randomly two particles to one or two different observers, named here random destination sources (RDS), cannot by used for genuine quant…
Multiparty multilevel energy-time entanglement
G. Vallone, P. Mataloni, A. Cabello
Franson-like setups are inadequate for multiparty Bell experiments with energy-time entanglement because postselected events can depend on the local settings, and local models can…
"All versus nothing" inseparability for two observers
Adan Cabello
A recent proof of Bell's theorem without inequalities [A. Cabello, Phys. Rev. Lett. 86, 1911 (2001)] is formulated as a Greenberger-Horne-Zeilinger-like proof involving just two ob…
