    "abstract": "We derive necessary and sufficient inseparability conditions imposed on the\nvariance matrix of symmetric qubits. These constraints are identified by\nexamining a structural parallelism between continuous variable states and two\nqubit states. Pairwise entangled symmetric multiqubit states are shown here to\nobey these constraints. We also bring out an elegant local invariant structure\nexhibited by our constraints.",
