- Abstract: Quantifying entanglement is an important issue in quantum information theory.
Here we consider the entanglement measures through the trace norm in terms of
two methods, the modified measure and the extended measure for bipartite
states. We present the analytical formula for the pure states in terms of the
modified measure and the mixed states of two-qubit systems for the extended
measure. We also generalize the modified measure from bipartite states to
tripartite states.

An entanglement measure based on the Fubini-Study metric has been recently introduced by Cocchiarella and co-workers.
We present the Gaussian Entanglement Measure (GEM), a generalization of geometric entanglement measure for multimode Gaussian states.
By providing a computable multipartite entanglement measure for systems with a large number of degrees of freedom, we show that our definition can be used to obtain insights into a free bosonic field theory.
