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...
Geometric measure of quantum discord for an arbitrary state of a bipartite quantum system
Geometric measure quantum discord for arbitrary state bipartite quantum system
2010/11/4
Quantum discord, as introduced by Olliver and Zurek [Phys. Rev. Lett. \textbf{88}, 017901 (2001)], is a measure of the discrepancy between quantum versions of two classically equivalent expressions fo...
An Experimentally accessible geometric measure for entanglement in $N$-qudit pure states
An Experimentally accessible geometric entanglement $N$-qudit pure states
2010/4/8
We present a multipartite entanglement measure for $N$-qudit pure states, using the norm of the correlation tensor which occurs in the Bloch representation of the state. We compute this measure for im...
