Data set for manuscript " Coherent manipulating a self-trapped triplet-exciton qubit in polymers "

This data set provides the code, calculation results, and the corresponding discussions of the work "Coherent manipulating a self-trapped triplet-exciton qubit in polymers ". In this work, we theoretically propose a scheme for the coherent manipulation of a single qubit, which is constructed using a self-trapped triplet exciton (STTE) in FM/polymer/FM sandwitch. The STTE serves as a quantum dot, comprising two degenerate triplet states with opposite magnetizations, thereby forming the qubit's subspace. We demonstrate that the spin state of this qubit can be coherently manipulated by applying an external circular polarized light (CPL). We further reveal that this manipulation exhibits significant helicity dependence.
