Open Compute Project Sets the First-Ever Data Centre Standards for Quantum Processing Units

[TomTiz]

The Open Compute Project Foundation published a landmark framework on June 27 for integrating Quantum Processing Units into data centres, authored by a consortium including the UK's National Quantum Computing Centre, Dell Technologies, Nvidia, IBM, Pasqal, D-Wave, IonQ, IQM and Diraq. The framework redefines quantum systems from isolated laboratory hardware into modular, rack-schedulable enterprise infrastructure assets for the first time. Previously there were no agreed standards for how a QPU should physically slot into a data centre, how it should interface with classical compute, how it should be cooled or what electrical specifications it should meet.

The practical architecture described in the OCP framework creates a layered stack: a classical AI and HPC fabric at the top running Nvidia NVL72-class hardware, connected through PCIe and NVQLink networking to a real-time control plane, which manages signal translation to the physical quantum processor vault. The quantum vault itself accommodates different qubit modalities, including superconducting systems requiring dilution refrigeration at 10 millikelvin and neutral-atom or photonic systems that operate at room temperature. The framework includes facility zoning specifications for each modality and thermal management requirements.

The strategic context is that data centre investment horizons have extended from two to three years to five to ten years as quantum timelines have come into planning range. Without standardisation, operators face bi-directional asset stranding: classical infrastructure built incompatibly with future quantum systems, and quantum systems incompatible with existing classical infrastructure. The OCP framework provides the forward-compatible specification that infrastructure planners need to build quantum-ready facilities now without waiting for quantum hardware to mature fully.

OCP standards for QPU integration are the same standardisation moment that x86 PC architecture was for personal computers in the early 1980s. Before that standard you had incompatible hardware everywhere. After it you had an industry. This is the beginning of that transition for quantum

The layered stack architecture described, classical AI fabric at the top, real-time control plane in the middle, quantum vault at the bottom, is exactly the hybrid quantum-classical architecture that the research community has been describing theoretically for years. Seeing it codified in an OCP standard is a different kind of reality check

Photonic quantum systems operating at room temperature and superconducting systems requiring 10 millikelvin sitting in the same standard is the framework's most practically ambitious claim. Getting those two modalities into adjacent rack specifications while the cooling requirements differ by orders of magnitude is a serious engineering challenge

The authors including Nvidia confirms what CUDA-Q and NVQLink announcements have been signalling: Nvidia wants to be the connectivity layer between quantum and classical compute in the same way it became the connectivity layer between CPUs and accelerators

Ten-year data centre investment horizons being driven by quantum integration planning is a shift in how infrastructure operators think. Hyperscalers are being asked to design buildings today for hardware that does not yet exist at commercial scale. The OCP framework gives them something concrete to design around

IQM, Pasqal, D-Wave and IonQ all contributing to the same standards document despite being direct competitors in the quantum hardware market is the industry self-interest alignment that makes OCP frameworks credible. Nobody wants to be the incompatible outlier

The UK's NQCC being a co-author of an OCP framework produced alongside American technology companies is the kind of transatlantic quantum cooperation that the Trump executive orders and UK national quantum strategy are both trying to accelerate
