Menlo Microsystems Inc. and Rosenberger are collaborating on a multichannel ultra-low power switch module designed to accelerate scalable quantum systems.

The partnership combines Menlo Micro’s Ideal Switch microelectromechanical systems (MEMS) technology with Rosenberger’s high-density multichannel WSMP RF connector and industrialization experience.

The combo module is targeted at a bottleneck in quantum system interconnect and control infrastructure. The collaboration will work to commercialize quantum computing by delivering a cryogenic switching solution from pathway to deployment.

The Ideal Switch MEMS is capable of operation down to 10 millikelvins (mK). Minimizing Joule heating and maintaining near-zero temperature disturbance during switching allows the module to improve thermal efficiency, simplify system design and offer compact, dilution refrigerator-compatible form factor for next-generation quantum systems.

“This partnership marks a major milestone in making scalable quantum systems more practical and efficient,” said Russ Garcia, CEO of Menlo Micro. “By combining our Ideal technology with Rosenberger’s world-class cryogenic interconnects, precision connectivity, and proven reliability, we aim to provide a modular solution that reduces system complexity and helps quantum system developers shorten development cycles and accelerate time to market for their applications.”
