Menlo Micro and Purdue Demonstrate Cryogenic MEMS Switching for Scalable Quantum Systems

Menlo Microsystems, in collaboration with Purdue University, has demonstrated a commercial-ready architecture for quantum control and readout electronics operating at cryogenic temperatures. The research, published in Nature Microsystems & Nanoengineering, highlights the use of Menlo Micro’s MEMS-based Ideal Switch technology in scalable quantum computing systems.

The study addresses a key bottleneck in quantum architectures: the complex interconnect between room-temperature electronics and cryogenic quantum processors. By using MEMS-based multiplexers capable of operating at cryogenic temperatures, the researchers reduced wiring complexity, thermal load and overall system cost.

Tests conducted at approximately 5.8 kelvin showed low insertion loss below 0.5 dB and isolation of about 35 dB. The team also demonstrated NAND and NOR logic gate operations at cryogenic temperatures, indicating that MEMS switches could support local control functions closer to the quantum processor.
