| 抄録 | In quantum networks quantum information is processed by exchanging quantum states between physical systems. It has been studied to trap and cool ions for quantum information processing to build a prototype of the quantum network. There has been found (43)Ca(+) as the best candidate for the qubit in the quantum network. The schemes for quantum gate operations and for quantum state transfer with the ion species are discussed. There have been developed a ring ion trap and a light source consisting of violet diode lasers for realizing the schemes. There has been achieved deterministic coupling of a single (40)Ca(+) to the optical field in a cavity. |
