Cryogenic- and Quantum Technology

 

Unlocking the Potential of Quantum Computing

Quantum computing stands at the forefront of technological advancement, promising to redefine the limits of computational power and revolutionize industries across the globe. Unlike classical computers, which process information in binary bits, quantum computers leverage the principles of quantum mechanics to operate with qubits, enabling them to perform complex calculations at an unprecedented scale and speed.

At Rosenberger, we're deeply immersed in the world of quantum computing, where the future of computational power is being reshaped. Leveraging our extensive expertise in the RF domain and close collaboration with leaders in quantum technology, we have a profound understanding of the intricate requirements for connectivity solutions in ultra-low temperature environments.

 

Meeting Quantum Connectivity Requirements

Quantum computing demands RF connectors with highly specific interconnect features, including:

  • Ability to withstand cryogenic temperatures
  • High-frequency components
  • Non-magnetic coaxial connectors and cable assemblies
  • High-isolation delivery of electromagnetic control signals and microwave connectivity solutions
  • Low RF loss

We understand these requirements intimately. To mitigate the effects of thermal fluctuations, electromagnetic radiation, and magnetic fields within the refrigeration system, we offer a diverse range of solutions for cryostatic applications. Our robust product portfolio is complemented by state-of-the-art precision manufacturing capabilities, enabling us to deliver nearly limitless custom solutions. As the demand for higher connection densities, smaller connectors, and multichannel connectors grows, we remain committed to providing cutting-edge components and complete sub-systems for any Dilution Refrigerator installation.

 

Our Quantum Connectivity Offerings

Customized Hermetical Adaptor Flanges

Our hermetically sealed adaptor flanges, designed to secure high vacuum with glass-to-metal sealing made from Kovar and plated with gold, can be tailored to meet specific customer design requirements.

We offer multi-channel flanges and can achieve specified leakage rates up to ≀ 10-8 mbar * l/s, along with 100% fine leakage tests.

 

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 and superconducting cable assemblies using special soldering processes.

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.

 

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.
