Detection and quantification of entanglement in quantum resources are two key steps in the implementation of various quantum-information processing tasks. Here, we show that Bell-type inequalities are not only useful in verifying the presence of entanglement but can also be used to bound the entanglement of the underlying physical system. Our main tool consists of a family of Clauser-Horne-like Bell inequalities that cannot be violated maximally by any finite-dimensional maximally entangled…

Device-independent entanglement quantification and related applications.
It is shown that the method presented provides a rigorous way to construct dimension witnesses, gives new insights into the question whether bound entangled states can violate a Bell inequality, and can be used to construct device-independent entanglement witnesses involving an arbitrary number of parties.
Semi-device-independent characterization of multipartite entanglement of states and measurements
The semi-device-independent framework allows one to draw conclusions about properties of an unknown quantum system under weak assumptions. Here we present a semi-device-independent scheme for the
Measurement-device-independent quantification of entanglement for given Hilbert space dimension
This work addresses the question of how much entanglement can be certified from the observed correlations and the knowledge of the Hilbert space dimension of the measured systems and presents security proofs of quantum key distribution without any assumption on the measurements.
Family of Bell-like Inequalities as Device-Independent Witnesses for Entanglement Depth.
We present a simple family of Bell inequalities applicable to a scenario involving arbitrarily many parties, each of which performs two binary-outcome measurements. We show that these inequalities
Linking entanglement detection and state tomography via quantum 2-designs
An experimentally feasible and efficient method for detecting entangled states with measurements that extend naturally to a tomographically complete set, and is twice as effective as standard witnesses in the sense that both upper and lower bounds can be derived.
Device-Independent Witnesses of Entanglement Depth from Two-Body Correlators.
This work obtains device-independent witnesses of entanglement depth (DIWEDs) using the Bell inequalities introduced in [J. Tura et al], and obtains a certificate of optimality via a semidefinite program, based on a relaxation of the quantum marginal problem, which suggests a clear pattern on k-producible bounds for large system sizes.
Geometrical self-testing of partially entangled two-qubit states
It is shown that, when a set of correlators in the simplest Bell scenario satisfies a condition, the geometry of the state vectors is uniquely determined, and a geometrical scheme for self-testing is superior in that a realization with an arbitrary number of measurements can be self-tested.
Experimental semi-device-independent certification of entangled measurements.
The procedure is termed semi-device-independent, as it uses uncharacterized quantum preparations of fixed Hilbert space dimension and experimentally certify an entangled measurement using only measurement statistics.
Entanglement estimation from Bell inequality violation
It is well known that the violation of Bell’s inequality in the form given by Clauser, Horne, Shimony, and Holt (CHSH) in two-qubit systems requires entanglement, but not vice versa, i.e., there are
Cryptographic quantum bound on nonlocality
It is shown that no-signaling resources of pure partially entangled states produce randomness in the communication bits, and achievement of the maximum limit is impossible, i.e., the information causality principle is insufficient for the full identification of the quantum boundaries already for bipartite settings.
