Quantum Technology Projects

Rosenbergers part in this project is

• Development of a temperature-stable connector interface that can be further developed into a multiport connector, having as a feature less than 3 mm channel pitch.
• Development and production of planar substrates for attenuators that can be integrated into the connectors and matching their channel pitch.
• Deepening the knowledge of soldering niobium-titanium cables, especially in multiport connectors.
• Deepening the knowledge of soldering stainless steel cables, especially in multiport connectors.

Rosenberger is researching the feasibility of miniaturized, multiport connectors as a connectivity solution suitable both for flat ribbon conductors based on polyimide and for additive cables. These connectors have to be suitable for applications in high vacuum and at lowest temperatures. In detail it is about

• Connectors with approx. 80 channels, suitable for the flat cable solution introduced by the partners Supracon and LPKF. In addition the connectors can be attached to our own, additively manufactured coaxial flat ribbon cables
• Development of suitable flange feedthroughs
• Research and development of practicable flat ribbon coaxial cables produced by additive technology
• Pitch of the channels on the cable < 1 mm, minimal expansion in the attachment area
• Use of materials with low thermal conductivity
• Ensuring functionality down to the millikelvin range
• Excellent RF properties according to specification, frequency range up to 12 GHz
