A two qubits system interacting with two independent spin‐environments connecting with the third environment is constructed in order to demonstrate the effect of the multi‐environment for quantum correlation. In this process, the freezing phenomenon appears for SCI and X states under Quantum Discord and Geometric Discord measures, respectively, but not for the same initial state measured by different measures. Meanwhile, the properties of the freezing platform, characterized by the collapse, revival and persistent time, are researched by the different parameters. The result of this paper may pave a way to control quantum correlation and design nanospintronic devices.
The interacting muti‐environment affects the properties of quantum correlation, even if some environments do not directly interact with the system. The freezing behavior emerges only by the QD or GD method under the same conditions and can be effectively affected by the intrinsic parameters (the coupling parameter b between the spin particles and environments, the environment's temperature T and the coupling parameters q between the environments).
