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.

本数据集提供了题为《聚合物中自束缚三重态激子量子比特的相干操控》的研究工作的代码、计算结果及对应讨论。本工作从理论上提出了一种单量子比特的相干操控方案，该量子比特由铁磁体（FM）/聚合物/铁磁体（FM）三明治结构中的自束缚三重态激子（STTE）构建而成。该自束缚三重态激子充当量子点，包含两个具有相反磁化强度的简并三重态，由此构成该量子比特的子空间。我们证明了，可以通过施加外部圆偏振光（CPL）对该量子比特的自旋态进行相干操控。我们进一步揭示，该操控过程表现出显著的螺旋度依赖性。
