We investigate a family of mixed entangled states wherein there exist common stabilizers among the mixtures of the corresponding density matrix. The nonlocality of these mixed entangled states can be verified by the maximal violation of stabilizer-based Bell-type inequalities. Some of these states with specific probability distributions are bound entangled, which can be superactivated. Potential applications of these mixed states in quantum key distribution and quantum repeaters are also introduced.
