Geometric Entanglement of Symmetric States and the Majorana Representation
Geometric Entanglement Symmetric States Majorana Representation
2010/11/8
Permutation-symmetric quantum states appear in a variety of physical situations, and they have been proposed for quantum information tasks. This article builds upon the results of [New J. Phys. 12, 0...
Connections of geometric measure of entanglement of pure symmetric states to quantum state estimation
Connections geometric measure entanglement pure symmetric states quantum state estimation
2010/11/5
We study the geometric measure of entanglement (GM) of pure symmetric states related to rank-one positive-operator-valued measures (POVMs) and establish a general connection with quantum state estimat...

Collective photon emission symmetric states Rydberg atoms

We discuss the creation of non-classical light from collective atomic states that are prepared in a ring-shaped lattice. These states are realized by exploiting the strong interaction between atoms in...
Entanglement and symmetry in permutation symmetric states
Entanglement symmetry permutation symmetric states
2010/3/10
We investigate the relationship between multipartite entanglement and symmetry, focusing on permutation symmetric states. We use the Majorana representation, where these states correspond to points on...
