Abstract

We theoretically analyze the yield and fidelity of the quantum state transfer (QST) from a photon polarization qubit to an electron spin qubit using a spin-coherent photo-detector consisting of a semiconductor quantum dot. We use the modified one-dimensional light-atom interaction model which includes parameters such as photon-dot interaction, the tunneling rate of the created hole, the bandwidth of the input photon, and the electron-hole exchange interaction. The electron-hole exchange interaction disturbs the electron spin state and thus decreases the fidelity of the QST. We find the optimal conditions in which both a high-yield and high-fidelity QST is realized.
