日本 IQuantum www.iquantum.jp
Based in Tsukuba Science City, Japan, IQUANTUM continues to create one-of-a-kind measurement products and services. 

IQUANTUM is a company spun off the National Institute of Advanced Industrial Science and Technology (AIST), Japan. 
Based on AIST's long history of low-temperature and precision-measurement research since one of its predecessors, Electrotechnical Laboratory, IQUANTUM offers unprecedented products and services that take you to new frontiers. 
These include a 3He insert for the de facto standard SQUID magnetometer, an AC/DC transfer standard, and a cryogen-free programmable Josephson voltage standard. 
We wish to develop new products through marketing that ties our technological seeds and customers' needs. Please feel free to contact us.
