Kryogenisk- og kvanteteknologi

Forbindelsesteknologi til fremtidens kvanteverden

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.

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.
