Bluefors and Qblox Announce Collaboration to Advance Quantum Computing Infrastructure

Insider Brief:

• Bluefors and Qblox signed a Memorandum of Understanding to collaborate on integrated solutions for quantum technologies, focusing on spin qubit systems.

• At APS Global Physics Summit 2025, they will demonstrate Qblox’s quantum computing control stack working with Bluefors’ cryogenic measurement systems.

• The partnership aims to improve quantum infrastructure, enabling faster development of scalable quantum processors for industrial applications.

PRESS RELEASE — In a recent release, Bluefors, a leading manufacturer of cryogenic measurement systems for quantum technologies, and Qblox, a provider of scalable quantum computing control stacks, announced they have signed a Memorandum of Understanding to develop integrated solutions for quantum computing. The collaboration will focus on improving infrastructure for spin qubit-based quantum processors, a platform that is gaining attention for its potential scalability and compatibility with existing semiconductor technologies.

As noted in the announcement, the two companies will present a joint demonstration at Qblox’s booth (#139) during the APS Global Physics Summit 2025. The demonstration will showcase Qblox’s quantum control stack operating in tandem with Bluefors’ cryogenic measurement systems, highlighting the compatibility of their technologies in a practical quantum computing setup.

Addressing Infrastructure Challenges for Spin Qubits

Spin qubits, typically based on electron or nuclear spins in semiconductor quantum dots, require precise cryogenic control to maintain coherence and perform high-fidelity quantum operations. Bluefors specializes in dilution refrigerator systems that provide the ultralow temperatures needed to stabilize these qubits. Qblox, in turn, develops control hardware optimized for large-scale quantum processors, including high-performance microwave and RF electronics for precise qubit manipulation.

The collaboration is intended to refine the integration between these components. As noted in the release, Mikko Nurminen, Chief Sales Officer of Bluefors, stated: “Our collaboration with Qblox will accelerate development of solutions for spin qubit customers. Improving the integration of innovative technologies in quantum computing infrastructure is essential for advancing the field and paving the way for utility-scale adoption of quantum computing.”

Integration as a Key to Scaling Quantum Processors

A notable challenge in building practical quantum computers is ensuring seamless interaction between cryogenic environments and quantum control electronics. Many existing setups rely on customized, ad-hoc integration efforts, limiting scalability and reliability. By combining Bluefors’ expertise in cryogenic platforms with Qblox’s modular control stacks, the partnership may streamline this process, reducing complexity for researchers and companies developing spin qubit processors.

According to the announcement, Qblox CEO Niels Bultink emphasized the necessity of a tightly integrated approach: “Industrial-scale quantum computers will require tight integration of cryogenic environments and control stacks. By innovating together, we make sure that our customers can develop their quantum processors faster and reach scales and fidelities that are required for quantum advantage”

Toward Integrated Solutions

This collaboration reflects a broader trend in quantum computing, where hardware providers are moving toward more integrated, application-ready solutions. By addressing system-level challenges, the two companies will directly support the development of scalable quantum architectures that can transition from research labs to industrial applications.

Both companies have extensive experience working with quantum computing groups worldwide. Bluefors’ dilution refrigerators are used by widely recognized research institutions and commercial quantum initiatives, while Qblox’s modular control electronics support multi-qubit platforms in Europe and North America.

The joint demonstration at APS Global Physics Summit 2025 will offer a preview of how these technologies can work together, providing researchers and industry stakeholders with insights into the next potential steps for scalable quantum computing.
