Abstract

In quantum networks quantum information is processed by exchanging quantum states between physical systems. We have studied trapping and cooling of ions for quantum information processing to build a prototype of the quantum network. We have found 43Ca + 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. We have developed a ring ion trap and a light source consisting of violet diode lasers for realizing the schemes. We have achieved deterministic coupling of a single 40Ca + to the optical field in a cavity.
