| Abstract: | We demonstrate the generation of a Werner-like state from a single semiconductor quantum dot. The tomographic analysis with temporal gating brings us to a systematic understanding of the relation between the time evolution of quantum correlation and a set of parameters characterizing the exciton states, including fine-structure splitting and cross-dephasing time. The Werner state relates the Bell's parameter in the Clauser, Horne, Shimony, and Holt inequality with a fidelity, which facilitates the evaluation of nonlocality. |
