- Abstract: Exploiting the notion of measurement-induced nonlocality [Phys.Rev. Lett.
106, 120401 (2011)], we introduce a new measure to quantify the nonbilocal
correlation. We establish a simple relation between the nonlocal and nonbilocal
measures for the arbitrary pure input states. Considering the mixed states as
inputs, we derive two upper bounds of affinity-based nonbilocal measure.
Finally, we have studied the nonbilocality of a different combinations of input
states.

We re-visit the generation and evolution of (Bell) nonlocality in hybrid scenarios whose dynamics is determined by the Jaynes-Cummings Hamiltonian.
Recent results on the optimal Bell violation in qubit-qudit systems show that the nonlocality is much greater than previously estimated.

We show that breaking the positive-semidefinite requirement allows for the construction of states that are nonlocal under one component labelling but local when the labelling is interchanged.
This is an observer-dependent nonlocality, showing the connection between nonlocal objectivism and negative quasi-probabilities.

Nonlocality, manifested by the violation of Bell inequalities, indicates quantum entanglement in the underlying system.
We quantify entanglement using a family of generalized Clauser-Horne-Shimony-Holt-type Bell inequalities.

A set of correlations is said to be nonlocal if it cannot be reproduced by spacelike-separated parties sharing randomness and performing local operations.
We show that there exist (efficient) local producing measurements that cannot be reproduced through randomness and quantum-time computation.

Nonlocality in networks gives rise to phenomena radically different from that in standard Bell scenarios.
We experimentally observe full network nonlocality in a network where the source-independence, locality, and measurement-independence loopholes are closed.
Our experiment violates known inequalities characterizing non-full network nonlocal correlations by over five standard deviations.

We define an alternative way of quantifying nonlocality of states based on Bell nonlocality of behaviors, called the trace-weighted nonlocal volume.
The construction is based on the nonlocal volume, a quantifier of nonlocality for states that counts the volume of the set of measurements that give rise to nonlocal behaviors when applied to this state, plus the trace distance.
We show that the weak anomaly of nonlocality for the (2, 2, 3) scenario persists, but the local minimum for nonlocality with the trace-weighted nonlocal volume occurs in a different state as compared to the minimum for the

We exploit the notion of measurement-induced nonlocality (MIN) and advocate a fidelity based nonbilocal measure.
We show that the properties of the fidelity based nonbilocal measure are retrieved from that of MIN.
We evaluate the nonbilocal measure for any arbitrary pure state.
