Here you will find some information on terminated projects and events of working group 2.43.

We hosted the Workshop Kryoelektronische Bauelemente (KRYO 2019) in autumn 2019. Further information of this workshop are collected at KRYO 2019.

We were also contributing to the EMPIR project "QuADC - Waveform metrology based on spectrally pure Josephson waveforms" with a runtime from June 2016 to May 2019. This poject focused on the development of voltage measurement systems for the metrology-grade waveform analysis (further reading: QuADC).

The final report and further informationen are available via the EURAMET website (QuADC).

Within the framework of the European Metrology Research Programme (EMRP), we coordinated the project "Q-WAVE - A quantum standard for sampled electrical measurements" with a runtime from June 2013 to May 2016. The aim of Q-WAVE was to provide direct and efficient traceability of voltage measurements for precision devices operating at frequencies up to 10 MHz (further reading: Q-WAVE).

The final report and further information are available via the EURAMET website (Q-WAVE).

In the framework of the MNPQ project "Transfer und technologische Verbesserungen von Schaltungen aus überdämpften Josephson-Kontakten für programmierbare Josephson-Spannungsnormale" (MNPQ-Transfer-Nr. 08/08), the fabrication technology was significantly improved in close cooperation with the company Supracon AG in Jena. Main results of this national project with a runtime from Aug. 2009 to Aug. 2011 are summarised in this Report (in German).

AC Josephson voltage standards have partly been developed within the framework of national and international projects, especially within the framework of the iMERA-Plus project JoSy, Next generation of quantum voltage systems for wide range applications (T4.J03) that was funded from March 2008 to Feb. 2011.

Within a close co-operation with FLUXONICS e. V., the support action S-PULSE was formed. S-PULSE, namely Shrink-Path of Ultra-Low Power Superconducting Electronics, was funded by the EU within the Seventh Framework Programme for Research and Technological Development (FP7) from Jan. 2008 to June 2010.

Within the framework of the S-PULSE project, we organized the workshop "Applied Superconductor Electronics in Quantum Metrology" in May 2009.
 

We hosted the Workshop Kryoelektronische Bauelemente (Kryo 2008) in October 2008. Information of this workshop are collected at the press release of PTB (in German) and the IEEE CSC European Superconductivity News Forum.
