Cryogenic and Quantum Technology

 

Connection Technology for Tomorrow's Quantum World

Quantum computers are considered a key technology for future scientific and industrial innovations. However, operating such systems requires connection technology that works reliably even under the most extreme conditionsβ€”especially at temperatures close to absolute zero. Rosenberger meets these requirements with a wide-ranging portfolio: from RF connectors for low-temperature applications, non-magnetic coaxial connectors, and superconducting cables to hermetically sealed vacuum feedthroughs.

 

Due to many years of expertise in the RF field and intensive contact with several customers in this application field. Rosenberger understands the challenges and demands for current and future needs in cryogenic and quantum technology.

Therefore a wide range of parts and possibilities for such applications can be offered. Meeting the requirements for higher number of connections, smaller connectors and multichannel connectors will be more important for the future.

The same requirements exist for hermetic adaptors, attenuators and cable assemblies. Regarding this, Rosenberger also works on new solutions for future requirements.

 

New Multichannel WSMP® Series

The new multichannel WSMP® connectors are based on the Rosenberger WSMP® interface which is standardized according to IEC 61169-69 (SMP3) and designed for maximum packing density. They were developed specifically for use in quantum computers as part of a funded project (qBriqs) and have been tested by project partners.

Cable Assemblies

Rosenberger has a wide range of standard cable assemblies (flexible, semi-flex, semi-rigid) and manufacture also customized cable assemblies on request.

In addition to the standard cable assemblies, Rosenberger also has the capabilities to manufacture special semi-rigid cable assemblies for cryogenic applications and superconducting cable assemblies with special soldering processes. As a result, such cable assemblies have excellent electrical and mechanical properties on the solder joints.

  • Non-magnetic cable assemblies
  • Stainless Steel cable assemblies
  • CuproNickel cable assemblies
  • NiobiumTitanium cable assemblies
 

Complete Sub-Systems

Rosenberger provides customized solutions and partnerships.

For customer projects Rosenberger can design, construct and manufacture complete sub-system for cryogenic and quantum applications like coax-sticks, sample pucks or anything else which is made out RF and mechanical components.

 

Strong Partner for Research and Industry

Thanks to its many years of RF expertise and close cooperation with leading research institutes and industry partners, Rosenberger is making a significant contribution to transferring quantum technologies from the laboratory to practical applications.
