| Outline of Final Research Achievements |
We studied superconducting (SC) qubits as “Artifical Atoms” and asked similar questions researchers have asked for natural atoms (including how these “giant atoms” interact with light, transmission lines, electro-magnetic resonators, mechanical resonators, etc.). We theoretically studied the interdisciplinary field involving quantum optics, atomic physics, condensed matter physics, nanoscience, and computer science. These types of problems include how photons interact with qubits, lasing phenomena using superconducting qubits; single-photon generators; photon-number control (Fock state generation); coupling qubits by a resonator; coupling resonators by a qubit; and also quantum measurements. This is a growing interdisciplinary area of research. We obtained many interesting results, which were featured in top physics journals.
