Effect of Entanglement on Geometric Phase for Multi-Qubit States

When a multi-qubit state evolves under local unitaries it may obtain a geometric phase, a feature dependent on the geometry of the state’s projective Hilbert space. A correction term to this geometric phase in addition to the local subsystem phases may appear from correlations between the subsystems. We find this correction term can be characterized completely either by the entanglement or comp...

Geometric multipartite entanglement measures

We report on a geometric formulation of multipartite entanglement measures which sets a generalization of the partial formulation of a few-qubit entanglement scenario reported in Ref. [1]. By means of the permutation group of N = 3 elements, we first propose a measure which satisfactorily reproduces the entanglement values reported in the literature for tripartite entangled states. We then give...

Revised Geometric Measure of Entanglement

We revise the geometric measure of entanglement (GME). The revised geometric measure of entanglement (RGME) is an entanglement monotone. Some useful inequalities about RGME are deduced. As the RGME’s application, the twoparameter class of states in 2⊗ n quantum system, the two particles high dimensional maximally entangled mixed state, the isotropic state including n-particle d-level case and t...

An Entanglement Study of Superposition of Qutrit Spin-Coherent States

Considering generalized concurrence as the criterion of entanglement, we study entanglement properties of superposition of two qutrit coherent states, as a function of their amplitudes. These states may attain maximum entanglement or no entanglement at all, depending on the choice of the parameters involved. The states revealing maximum entanglement also display the maximum violations of the Be...
