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 conditions—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.

 

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.

Benefits

  • Compact design for space-saving integration
  • Optimized connection to the thermal stages in the cryostat
  • Full integration of ceramic attenuators

Features

  • Additional mechanical fixing via screws
  • Anti-rotation protection
  • Copper based non-magnetic materials with AuroDur® plating
  • Channel 1 marking
  • Connection to the thermal stages in the cryostat via adaptors and attenuators
  • UT-047 semi-rigid cable assemblies made from various materials (stainless steel, cupro-nickel, niobium-titanium, beryllium-copper), others available on request
  • Flexible and semi-flex cable assemblies with different connectors on the second side as fan-out solutions

Specifications

  • Frequency Range: DC to 65 GHz
  • Interface: WSMP® (SMP3, IEC 61169-69)
  • Dimensions:
    • 16 channel (1 x 16, single row) – 4 mm x 50 mm
    • 32 channel (2 x 16, double row) – 6 mm x 50 mm
  • Pitch: 2.45 mm
  • Mating cycles: ≥ 500
 

Customized Hermetical Adaptor Flanges

Our gold-coated adaptor flanges feature a Kovar glass-to-metal seal, achieve specified leak rates of up to ≤ 10-8 mbar * l/s, and can be customized to meet specific design requirements. 

In addition, they undergo 100% leak testing.

 

Complete Sub-Systems

For customer projects, Rosenberger provides customized solutions and partnerships. We can design, construct, and manufacture complete sub-systems for cryogenic and quantum applications, including coax-sticks, sample pucks or any other RF and mechanical components required.

 

Portfolio for Maximum Flexibility

In addition to the new Multichannel WSMP®, Rosenberger offers both standard components and customized solutions with additional interfaces.

Standard Products

  • PCB connectors
  • Cable connectors
  • Hermetically sealed adapters
  • Attenuators
  • Semi-rigid cable assemblies
  • Semi-flex cable assemblies
  • Flexible cable assemblies
 

Common Interfaces. Cable Sizes include .141”, .085” and .047” - more are available on request

 

Cable Assemblies

Rosenberger offers a wide range of standard cable assemblies (flexible, semi-flex, semi-rigid) and manufactures customized cable assemblies upon request. In addition to standard offerings, we specialize in crafting special semi-rigid cable assemblies for cryogenic applications.

Our cable assemblies exhibit excellent electrical and mechanical properties at the solder joints and are available in non-magnetic, stainless steel, CuproNickel, Beryllium Copper and NiobiumTitanium variants.

 

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. Initial projects with universities, start-ups, and OEMs are already underway.

“With the WSMP® multichannel series, we are closing a crucial gap in connection technology for quantum computers. Our customers are increasingly demanding compact, thermally optimized, and dense solutions—and that's exactly what we deliver with this new product platform.”
