Teleportations of quantum gates are very important in the construction of quantum network and teleportation-based model of quantum computation. Assisted with nitrogenvacancy centers, we propose several schemes to teleport the quantum CNOT gate. Deterministic CNOT gate may be implemented on a remote two-photon system, remote two electron-spin system, hybrid photon-spin system or hybrid spin-photon system. Each photon only interacts with one spin each time. Moreover, quantum channel may be constructed by all combinations of the photon or electron-spin entanglement, or their hybrid entanglement. Since these electron-spin systems have experimentally shown a long coherence time even at the room temperature, our schemes provide useful ways for long-distance quantum applications.

Abstract In a series of liquid Cu-Ga alloys, the 63Cu and 71Ga Knight-shift K was measured in a high temperature NMR-Spectrometer from 400 to 1200 °C. Alloying the Cu-Ga host with 2% Mn causes a strong change in K which comes mainly from nuclei in the nearest neighborhood (l.n.n.) of Mn. This gives a first estimate of the conduction electron spin polarisation close to Mn. The data are compared to previous results in the Cu-Al-Mn system.
