Self-testing tilted strategies for maximal loophole-free nonlocality

npj Quantum Information
The degree of experimentally attainable nonlocality, as gauged by the loophole-free or effective violation of Bell inequalities, remains severely limited due to inefficient detectors.

Maximal quantum randomness in Bell tests

, 2012
The non-local correlations exhibited when measuring entangled particles can be used to certify the presence of genuine randomness in Bell experiments. While non-locality is necessary for randomness certification, it is unclear when and why non-locality ...

A paradox in bosonic energy computations via semidefinite programming relaxations

New Journal of Physics, 2013
We show that the recent hierarchy of semidefinite programming relaxations based on non-commutative polynomial optimization and reduced density matrix variational methods exhibits an interesting paradox when applied to the bosonic case: even though it can

Necessary and sufficient criterion for extremal quantum correlations in the simplest Bell scenario

, 2018
In the study of quantum nonlocality, one obstacle is that the analytical criterion for identifying the boundaries between quantum and postquantum correlations has not yet been given, even in the simplest Bell scenario. We propose a plausible, analytical,

Looking for symmetric Bell inequalities

, 2010
Finding all Bell inequalities for a given number of parties, measurement settings, and measurement outcomes is in general a computationally hard task. We show that all Bell inequalities which are symmetric under the exchange of parties can be found by ...

Maximal violation of a broad class of Bell inequalities and its implication on self-testing

Physical Review Research, 2019
In quantum information, lifting is a systematic procedure that can be used to derive—when provided with a seed Bell inequality—other Bell inequalities applicable in more complicated Bell scenarios.

Quantifying the intrinsic randomness in sequential measurements

New Journal of Physics
In the standard Bell scenario, when making a local projective measurement on each system component, the amount of randomness generated is restricted.
