Fidelity analysis of the photon‐spin quantum state transfer
Yoshiaki Rikitake, Hiroshi Imamura, Hideo Kosaka
We theoretically analyze yield and fidelity of the quantum state transfer (QST) from a photon polarization qubit to an electron spin qubit with a spin-coherent photo-detector consisting of a semiconductor quantum dot. We use the modified one-dimensional light-atom interaction model which include the parameters such as photon-dot interaction, tunneling rate of the created hole and the bandwidth of the input photon and the electron-hole exchange interaction. We find the optimal conditions where both the high-yield and high- fidelity QST is realized. (© 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
