Outline of Final Research Achievements

The aim of this research is to develop fundamental technologies for quantum information processing such as (1)quantum interface between photon-qubit carriers and atom-qubit memories, (2)efficient elimination of the destructive influence of the phase- and bit-errors in optical transmission lines, and (3)theoretical proposal of expansion/fusion gates for many-qubit entanglement. The results of our research turned out either as was expected or more than expected, depending on the research items. The resultant publications are 20 papers including Nature Photonics, Scientific Reports, New Journal of Phys., Phys. Rev. A, etc. We had 43 presentations at international conferences including 11 invited talks, 52 presentations at domestic conferences including 20 invited talks. Our research result was covered by a newspaper and many news sites on the Internet.
