Local sum uncertainty relations for angular momentum operators of bipartite permutation symmetric systems
文献摘要：
We show that violation of the variance based local sum uncertainty relation(LSUR)for angular momentum operators of a bipartite system,proposed by Hofmann and Takeuchi[Phys.Rev.A 68 032103(2003)],reflects entanglement in the equal bipartitions of an N-qubit symmetric state with even qubits.We establish the one-to-one connection with the violation of LSUR with negativity of covariance matrix[Phys.Lett.A 364 203(2007)]of the two-qubit reduced system of a permutation symmetric N-qubit state.
