US consortium to boost quantum cryo electronics

The Quantum Economic Development Consortium (QED-C) in the US is dedicated to advancing cryogenics in quantum technology to drive innovation and industrial competitiveness. QED-C was established with the goal of identifying gaps in enabling technologies and developing strategies to enhance cryogenics technology in quantum-based systems, spanning computers, sensors, and communications. A research program funded by the US National Institute of Standards and Technology (NIST) involved key industry players such as FormFactor, Northrop Grumman, Quantum Opus, and Triton Systems.

According to Celia Merzbacher, the Executive Director of QED-C, the cryogenics research program has yielded promising results. She stated, “We are proud of the results that our members are reporting as a result of the cryogenics research program. While work remains, thanks to these projects we are making steady progress in novel cryogenic technologies that are more energy efficient, compact, and affordable.” This collaborative effort aims to push the boundaries of cryogenics and unlock new possibilities in quantum technology.

Andrew Wilson, the technical lead for the NIST quantum research program, emphasized the importance of cryogenics in advancing quantum technologies. He expressed his enthusiasm for partnering with QED-C members to drive U.S. innovation and enhance industrial competitiveness. FormFactor, based in Livermore, California, made significant strides in developing new testing capabilities for quantum chips by streamlining cryogenic testing processes for complex dies and devices.

Quantum Opus, located in Michigan, focused on creating a low-cost, compact 2.5 K cooler to democratize access to quantum technologies. By exploring different technical paths, Quantum Opus made substantial progress in developing a commercially viable cryocooler that could revolutionize the quantum technology landscape. Triton Systems, based in Massachusetts, successfully demonstrated a fourth-stage expander for a Modified Collins Cycle cryocooler, enabling cryogenic devices to achieve temperatures between 4 K and 10 K.

Northrop Grumman, a prominent defense contractor, delved into the use of Porous Wall Hollow Glass Microspheres as a regenerator matrix for high-frequency Stirling type cryocoolers operating at ultra-low temperatures. While the research team identified key design constraints, further development is needed to fully leverage the potential of this innovative approach. The collective efforts of these industry leaders underscore the importance of cryogenics in propelling quantum technology forward.
