Dramatic progress of the superconducting quantum circuit technology during last decade has made
 the superconducting circuit as a key component in quantum information science. There is a non
-zero hope that a quantum computer might be someday built using Josephson junction based
 superconducting quantum bits ? The qubit. Superconducting qubit research requires multi
-disciplinary technologies such as device physics, materials science, microwave engineering, ultra
-low temperature physics and deep understanding of condensed-matter physics and quantum
 mechanics. After several years of intense research efforts, our team has developed and stabilized
 superconducting qubit technology so that various quantum measurements are now routinely
 performed in a single qubit system. Here I will introduce key progress and current status of
 superconducting qubit development and present recent experimental results of our group.
