Putting SQUIDs to Work

The superconducting quantum interference device (SQUID) is made of a superconducting loop and one or two Josepshon junctions. It is the most sensitive magnetic field detector. I will discuss some SQUID related projects on which my group is working. One is the development of a sensitive telescope camera for the SCUBA2 project. Another project is studying and trying to reduce the 1/f noise in the critical current of the Josephson junction. This low frequency noise is one of the fundamental limitations for making a high performance superconducting qubit for quantum computing.
