| Outline of Final Research Achievements |
In this research project, we have experimentally studied a universal set of quantum operations on states represented by optical frequencies. Optical quantum states are on ideal quantum system due to extremely low noise even at the room temperature. Furthermore, in optical frequency domain, the information can be encoded ultra-densely. In order to manipulate such states encoded in optical frequency domain, we developed a single photon frequency converter employing second order nonlinear crystal. In the case of 50% conversion efficiency, it acts as a beam splitter commonly used in standard optics. Using the frequency converter, we demonstrated Hong-Ou-Mandel interference and others to show the ability to the universal quantum operation.
