PTB has extensive expertise in fabrication of superconducting devices (WP1, WP2, WP4) and ultrafast optoelectronic measurements (WP2). In fact, PTB is beside NIST/USA the only NMI capable of fabricating JAWSs with voltage outputs exceeding 2 V. PTB’s JAWS circuits are operated at 9 NMIs worldwide. All JAWS circuits employed in the SuperQuant project will be fabricated at PTB. Moreover, PTB has invented a laser-based vector network analyzer, which will be extended to perform in-situ measurements in superconducting quantum circuits in WP2. So far, PTB has coordinated 5 relevant EMRP/EMPIR projects. PTB coordinates SuperQuant and leads WP2.

INRIM has extensive experience in quantum technology/metrology and RF&MW metrology fields. INRIM has consolidated fabrication and characterization capabilities for superconductive cryogenic nano and micro devices down to 10 mK (through Piquet fabrication infrastructure and dedicated laboratories) and has established metrological capabilities from 30 kHz to 50 GHz for both S-parameters and RF&MW Power quantities. So far, INRIM has participated in several projects dealing with superconductivity, optoelectronics and single photon counting at RF&MW: 3 EMRP/EMPIR projects (Parawave, ongoing, Microphoton, THz Security), 1 FET Open Project (SuperGalax, ongoing) and in two national projects (SIMP and DART WARS, both ongoing, both funded by Istituto Nazionale di Fisica Nucleare INFN). In SuperQuant INRIM leads WP3 and mainly contributes to S-parameters measurements.
