Abstract
The decay mechanism is considered in some nonlinear interaction models for two-qubit system. Exact expression of the final states of two-qubit are given for different model. We find that the maximal Wigner-Yanase skew information can be modulated and stored via using decay mechanism and nonlinear interaction. Due to the maximal Wigner-Yanase skew information being equivalent to the concurrence, the conditions of generating the maximally entangled state (i.e., the Bell state) are obtained.
