Entanglement and Volume Monogamy Features of Permutation Symmetric N-Qubit Pure States with N-Distinct Spinors: GHZ and
|
Abstract:
We explore the entanglement features of pure symmetric N-qubit states characterized by N-distinct spinors with a particular focus on the Greenberger-Horne-Zeilinger (GHZ) states and ![](\"https://html.scirp.org//file/1300400-rId16.svg?20240403024159\")
, an equal superposition of W and obverse W states. Along with a comparison of pairwise entanglement and monogamy properties, we explore the geometric information contained in them by constructing their canonical steering ellipsoids. We obtain the volume monogamy relations satisfied by ![](\"https://html.scirp.org//file/1300400-rId18.svg?20240403024159\")
states as a function of number of qubits and compare with the maximal monogamy property of GHZ states.
