N-qubit entanglement via the $J_y^2$-type collective interaction

Quantum Physics 2009-11-11 v1

Abstract

We investigate quantum correlations of the NN-qubit states via a collective pseudo-spin interaction (Jy2\propto J_y^2) on arbitrary pure separable states for a given interval of time. Based on this dynamical generation of the NN-qubit maximal entangled states, a quantum secret sharing protocol with NN continuous classical secrets is developed.
