Oxford Instruments NanoScience has completed the installation of the first two ProteoxQX systems, the largest and most modular dilution refrigerators in its Proteox product line. Designed to overcome current cryogenic limitations, the ProteoxQX enables deployment of significantly more qubits by offering a fully accessible workspace over 3 meters tall and 1.5 meters wide. The installation reflects growing customer demand for flexible, scalable cooling solutions as quantum processors expand in complexity and physical footprint.
A defining feature of the ProteoxQX is its modular architecture, incorporating four or six side-loading Secondary Inserts (SIs) that allow offline wiring and pre-characterization. This design enables rapid reconfiguration and reduced downtime by allowing one SI to run experiments while another is prepared. The SIs are interoperable across the ProteoxMX, ProteoxLX, and QX platforms, supporting lifecycle continuity from prototyping to full system deployment. Additionally, the QX expands on traditional design constraints by enlarging line-of-sight ports beyond the ISO100 standard, facilitating easier component integration without repeated rewiring.
The ProteoxQX architecture is intentionally designed for future scalability. Users can configure the system as a single large continuous mixing chamber or as independently controlled zones, adapting to evolving experimental needs. Its square geometry simplifies mechanical coupling of vacuum elements and radiation shields, enabling expansion as quantum hardware scales. Developed through close customer collaboration and presented at APS 2025, the ProteoxQX reinforces Oxford Instruments’ role as a core enabler of next-generation cryogenic environments for large-scale quantum computing research.
