Coherence and entanglement of fluorine impurity spin-qubits in ZnSe (A02)

本项目旨在研究ZnSe主体半导体中与氟给体杂质结合的电子自旋的相干性质。通过对Zn和Se的非零核同位素进行同位素纯化，可以降低甚至完全消除非零核自旋环境的强烈影响。ZnSe中的杂质束缚激子提供了强的光学跃迁，并将用于相干地操纵单个电子自旋，并证明驻留在两个远端杂质上的远端自旋之间的纠缠。

This project is aimed to study the coherent properties of electron spins bound to fluorine donor impurities in a ZnSe host semiconductor. The strong influence of the non-zero nuclear spin environment shall be reduced or even completely canceled by isotopic purification of the non-zero nuclear isotopes of Zn and Se. The impurity-bound excitons in ZnSe provide strong optical transitions and will be used to coherently manipulate individual electron spins and demonstrate entanglement between distant spins residing on two remote impurities.
