Interview
Advanced Cryogenics Systems
Summary
In this interview, David Gunnarsson, CBDO of Bluefors, discusses cryogenics in quantum computing, the company’s strong partnership with Quantum Machines, and what’s next for the field. Bluefors, a full-stack cryogenics company, provides solutions from 80 Kelvin down to a few millikelvin, specializing in cryogenic measurement infrastructure — an essential layer for quantum computers. David described it as a “complicated elevator” that connects room temperature to the extreme cold needed for quantum devices, where every step involves precise wiring, amplification, filtering, and integration. The conversation also highlighted how Quantum Machines complements Bluefors’ systems with filters and the Q-Cage sample holder, enabling a complete infrastructure solution for labs worldwide. Looking ahead, Bluefors is excited about newly launched products that expand cooling power, improve scalability, and introduce compact systems for easier integration of quantum computers. Both companies share the drive to push technology forward and continue delivering impactful innovations for their customers.
Highlights:
– Bluefors delivers cryogenic systems from 80K to millikelvin for quantum computing.
– Cryogenic measurement infrastructure is critical, acting like an “elevator” across temperatures.
– Partnership with Quantum Machines integrates QFilter and Q-Cage into Bluefors’ offering.
– New products: stronger cooling, flexible wiring, and an ultra-compact system for integration.
– Shared commitment to advancing quantum technology and scaling customer success.
