Abstract

We analyzed the yield and fidelity of the quantum state transfer (QST) from a photon polarization qubit to an electron spin qubit in a spin-coherent photo detector consisting of a semiconductor quantum dot. We used a model consisting of the quantum dot, where the QST is carried out, coupled with a photonic cavity. We determined the optimal conditions that allow the realization of both high-yield and high-fidelity QST.

Fidelity analysis of the photon‐spin quantum state transfer

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)

Effect of the electron-hole exchange interaction on the photon-spin quantum state transfer

Yoshiaki Rikitake, Hiroshi Imamura, Hideo Kosaka

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.

Effect of exchange interaction on the fidelity of quantum state transfer from a photon qubit to an electron-spin qubit

Yoshiaki Rikitake, Hiroshi Imamura

We analyzed the fidelity of the quantum state transfer (QST) from a photon-polarization qubit to an electron-spin-polarization qubit in a semiconductor quantum dot, with special attention to the exchange interaction between the electron and the simultaneously created hole. In order to realize a high-fidelity QST we had to separate the electron and hole as soon as possible, since the electron-hole exchange interaction modifies the orientation of the electron spin. Thus, we propose a double-dot structure to separate the electron and hole quickly, and show that the fidelity of the QST can reach as high as 0.996 if the resonant tunneling condition is satisfied.

Quantum State Transfer from a Single Photon to a Distant Quantum-Dot Electron Spin

Quantum state transfer from flying photons to stationary matter qubits is an important element in the realization of quantum networks. Self-assembled semiconductor quantum dots provide a promising solid-state platform hosting both single photon and spin, with an inherent light-matter interface. Here, we develop a method to coherently and actively control the single-photon frequency bins in superposition using electro-optic modulators, and measure the spin-photon entanglement with a fidelity of 0.796±0.020. Further, by Greenberger-Horne-Zeilinger-type state projection on the frequency, path, and polarization degrees of freedom of a single photon, we demonstrate quantum state transfer from a single photon to a single electron spin confined in an InGaAs quantum dot, separated by 5 m. The quantum state mapping from the photon's polarization to the electron's spin is demonstrated along three different axes on the Bloch sphere, with an average fidelity of 78.5%.

We present photon-spin quantum-state-transfer (QST) approach. GaAs/AlGaAs-QW with g~0 showed nonlinear B-field dependence of spin precession, suggesting photon-to-nuclei polarization transfer. 2DEG with quantum-point-contact on InGaAs/InP showed telecomwavelength-sensitive quantum transport. Efficient/high-fidelity QST conditions were also found.
