摘要：
We investigate the entangled property via spin squeezing in a 4-qubit state superposed by a GHZ state, W state and symmetric state with relative phases. Numerically solutions for spin squeezing parameter are derived. Mean spin direction and the spin squeezing parameters are determined by the superposition coefficients and the relative phases.
