Abstract: Elegant Bell inequality is well known for its much exploited property, being maximally violated by maximal entanglement, mutually unbiased bases, and symmetric informationally complete positive operator-valued measure elements. It is the only one with such property known so far. We present a method to construct Bell inequalities with violation feature analogous to original elegant Bell inequality in high dimension from a simple analytic quantum bound. A Bell inequality with such feature is derived in three dimension for the first time. It shows larger violation than existing Bell inequalities of similar classes while requiring arguably small number of measurements.

Bell Nonlocality from Wigner Negativity in Qudit Systems [1.2499537119440245]
We show that Wigner negativity is necessary for nonlocality in qudit systems. We propose a family of Bell inequalities that inquire correlations related to Wigner negativity of stabilizer states.

Optimal Bell inequalities for qubit-qudit systems [44.99833362998488]
We evaluate the maximal Bell violation for a generic qubit-qudit system, obtaining easily computable expressions in arbitrary qudit dimension. We also give simple lower and upper bounds on that violation and study the possibility of improving the amount of Bell-violation by embedding the qudit Hilbert space in one of larger dimension.

Some consequences of Sica's approach to Bell's inequalities [55.2480439325792]
Louis Sica derived Bell's inequalities from the hypothesis that the time series of outcomes observed in one station does not change if the setting in the other station is changed. In this paper, Sica's approach is extended to series with non ideal efficiency and to the actual time structure of experimental data.

An elegant proof of self-testing for multipartite Bell inequalities [0.0]
This work presents a simple and broadly applicable self-testing argument for N-partite correlation Bell inequalities with two binary outcome observables per party. To showcase the versatility of our proof technique, we obtain self-testing statements for N party Mermin-Ardehali-Bei-Klyshko (MABK) and Werner-Wolf-Weinfurter-.Zukowski-Brukner (WWW.ZB) family of linear Bell inequalities.

Optimality of any pair of incompatible rank-one projective measurements for some non-trivial Bell inequality [0.0]
Bell non-locality represents one of the most striking departures of quantum mechanics from classical physics. We show that for any pair of rank-one projective measurements, there exists a Bell inequality that is maximally violated by this pair. When investigating the robustness of these violations to noise, we demonstrate that the realization which is most robust to noise is not generated by MUBs.

Violation of general Bell inequalities by a pure bipartite quantum state [0.0]
We derive for a pure bipartite quantum state a new upper bound on its maximal violation of general Bell inequalities. We show that, for each of these bipartite coherent states, the maximal violation of general Bell inequalities cannot exceed the value $3$.

Bell's theorem for trajectories [62.997667081978825]
A trajectory is not an outcome of a quantum measurement, in the sense that there is no observable associated with it. We show how to overcome this problem by considering a special case of our generic inequality that can be experimentally tested point-by-point in time.
