Spin squeezing in Dicke-class of states with non-orthogonal spinors
arXiv:1901.02377 · doi:10.1088/1674-1056/28/6/060302
Abstract
The celebrated Majorana representation is exploited to investigate spin squeezing in different classes of pure symmetric states of N qubits with two distinct spinors, namely the Dicke-class of states. On obtaining a general expression for spin squeezing parameter, the variation of squeezing for different configurations is studied in detail.It is shown that the states in the Dicke-class, characterized by two-distinct non-orthogonal spinors, exhibit squeezing.
