Prof. Sillanpää has background in experimental superconducting nanoelectronics at milli-Kelvin temperatures. He has worked on Josephson junction quantum circuits and recently mostly on microwave optomechanics. Mika has developed low-noise amplification schemes based on microwave optomechanical concept, as well as carried out demonstrations in fundamental including quantum squeezing and entanglement of motion in micromechanical devices.
