Menlo Microsystems Inc. (Menlo Micro), a leader in high-performance electronic switches, announces a strategic partnership with Rosenberger to jointly develop a Multichannel Ultra-Low Power Switch Module for Quantum Computing, planned to accelerate scalable quantum systems.
The partnership combines Menlo Micro’s Ideal Switch® MEMS technology with Rosenberger’s precision high-density Multichannel WSMP RF connector and industrialization expertise, addressing a critical bottleneck in quantum system interconnect and control infrastructure.
This partnership positions Menlo Micro and Rosenberger to accelerate the commercialization of quantum computing by delivering modular, high-performance cryogenic switching solutions while providing the industry with a pathway to deploy practical, scalable quantum systems faster.
As quantum computing systems scale, managing RF signal routing at cryogenic temperatures becomes increasingly critical. Traditional switches generate thermal loads that can compromise qubit coherence and system stability. The planned Ultra-Low Power Switch Module is designed to integrate Menlo Micro’s ultra-low-power Ideal Switch platform, capable of operation down to 10 millikelvins (mK), with Rosenberger’s precision high-density16- and 32-Multichannel WSMP RF connector, engineered to deliver reliable, low-loss, and reproducible RF connections in cryogenic environments. To further support precise measurements, the module will include built-in Open-Short-Load (OSL) RF calibration standards, enabling rapid and repeatable system verification. By minimizing Joule heating and maintaining near-zero temperature disturbance during switching, the solution is expected to improve thermal efficiency, simplify system design, and offer a compact, dilution refrigerator-compatible form factor that supports higher-density characterization and production workflows and helps accelerate the development of next-generation quantum systems.
The partnership also underscores a strategic business opportunity in the rapidly growing quantum computing market. By combining Menlo Micro’s leading-edge switching technology with Rosenberger’s proven global interconnect solutions, the companies aim to reduce system complexity, accelerate development cycles, and support broader adoption of scalable quantum architectures.
As quantum computing transitions from research systems toward commercial deployments, the companies view this collaboration as an opportunity to establish a foundation for future product offerings that support long-term growth in quantum infrastructure markets.
“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 Switch 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.”
Stefan Brenner, Sales Director of Semicon and Test at Rosenberger, added, “Scalable quantum systems require robust, system‑level integration. Rosenberger contributes high‑density cryogenic interconnects, modular architectures, and industrialization expertise that enable reproducible and scalable RF connector systems. Together with Menlo Micro’s MEMS switching technology, we are addressing key challenges in multi‑channel quantum system design and integration.”
