The advancement of nanoscale science and technology is expected to realize the fusion of different scientific fields by removing the barriers between them and establish new scientific fields. In fact, various types of research have been carried out thus far. As the history of science indicates, science has developed alongside the development of new experimental technologies. It is important to obtain and analyze data by using existing devices and equipment; however, this is only one aspect of research. More important is the development of new experimental technologies, as has been demonstrated by the achievements of previous key research. The development of such new experimental technologies has been driven by strong demand from each scientific field. The Unit cooperates with other organizations by utilizing the advantages and favorable location of University of Tsukuba and aims to achieve significant progress in quantum technology research from the development of quantum devices to advances in life science and medicine by cooperating with researchers in such fields using the quantum measurement technology as the core technology.
