Measurement

The McDermott group has commissioned five low-temperature measurement platforms:

• Three adiabatic demagnetization refrigerators with base temperature around 50 mK. These systems are used for dc and microwave transport measurements and investigations of excess 1/f noise in Josephson devices.
• Two large-wire count dilution refrigerators with base temperature around 20 mK. These systems are dedicated to Josephson qubit measurements.

Device Fabrication

Our laboratory has two sputter deposition systems and one electron-beam evaporator for the growth of high-quality superconducting thin films and tunnel junctions.

The Wisconsin Center for Applied Microelectronics (WCAM) offers state-of-the-art facilities for thin film deposition and reactive ion etching, along with advanced UV projection lithography and electron beam lithography.
