Determining the whole pure symmetric N-qubit state from its parts

Abstract

The Majorana representation of symmetric N-qubit states is employed here to investigate how correlation information of the whole pure symmetric state gets imprinted in its parts. It is shown that reduced states of (N - 1) qubits uniquely specify the entire class of pure N qubit states containing two distinct spinors.
