- Abstract: We study the Bures measure of entanglement and the geometric measure of
entanglement as special cases of entanglement measures based on fidelity, and
find their tighter monogamy inequalities over tri-qubit systems as well as
multi-qubit systems. Furthermore, we derive the monogamy inequality of
concurrence for qudit quantum systems by projecting higher-dimensional states
to qubit substates.

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.

Entanglement -- the coherent correlations between parties in a quantum system -- is well-understood and quantifiable.
Despite the utility of such systems, methods for quantifying high-dimensional entanglement are more limited and experimentally challenging.
We present a novel certification method whose measurement requirements scale linearly with dimension subsystem.
