| Outline of Research at the Start |
Superconducting (SC) quantum circuits can act as artificial atoms made from electrical circuit elements. At very low temperatures, these circuits have quantized energy levels. Transitions between levels are induced by applying pulsed microwave radiation to the circuit, revealing quantum coherent phenomena analogous to (and in certain cases beyond) those observed with coherent atomic systems. SC quantum nano-devices are attracting growing interest worldwide and are being extensively studied for both basic science and future applications.

| Outline of Final Research Achievements |
We have obtained very many research achievements published in excellent physics journals, which were evaluated by many expert referees from all over the world. These research results are available to all in the ArXiv, and also in our web site, with the PDF files of all our publications. This is important for the public to freely access these research results. We have also made many research presentations to audiences. The PI has been listed as a Clarivate "Highly Cited Researcher” for the past six consecutive years: from 2017 to 2022 (less than 0.1% of physicists are selected, and less than ten in Physics in all of Japan). In 2023, the PI was elected Member of the Academia Europaea, and won the W. Lamb Medal, for research on Quantum Optics & Quantum electronics, the topics of this Kakenhi grant proposal.

| Academic Significance and Societal Importance of the Research Achievements |
Significant scientific results attract the attention of the research community, are evaluated by top referees from all over the world and are published in top journals. Top quality science is the only one that will have social impact.
