Dr Matteo Fretto achieved the degree in “Materials Engineering” in 2004 and the Ph.D in “Metrology: measuring science and techniques” in 2009 at the Politecnico di Torino. He is working in INRIM since 2005 and his main activity was focused on design, fabrication and testing of different superconducting quantum devices at the micro and nanoscale. He has contributed to the realization of a Programmable Josephson Voltage standards and to the implementation of a new fabrication technique based on Focus Ion Beam etching for 3D nanostructure and nano-Supercondutcing Quantum Interference Devices (nanoSQUIDs) realizaztion. He is autor and co-author of more than 40 international publications.
