"The Open Compute Project (OCP) has commenced a workstream to learn how to deploy quantum computers alongside classical high performance computers in the same datacenter. The org will gather experiences from the few facilities that have already deployed quantum systems and try to boil them down into "open specifications, best practices, and checklists that guide data center operators in preparing their infrastructure to accommodate quantum systems-ranging from cryogenic cooling and environmental controls to hybrid scheduling and orchestration frameworks.""
"Examples of such side-by-side installations already exist: IBM deployed a 20-qubit superconducting quantum computer at the Leibniz Supercomputing Centre (LRZ) and published a pre-press paper about the job. The document concluded that quantum computers have more stringent yet manageable environmental constraints and will need extra redundant infrastructure because outages can cause ten days of downtime while operators recalibrate quantum machines."
"But one does not just walk into a classical datacenter with a quantum computer, because the cryostat that keeps the machines cool weighs 750 kilograms. Designers must therefore ensure datacenters are ready to support 1000 kg/m ². Datacenter operators will also need to chill out, because liquid cooling for a cryostat assumes the availability of water at between 15°C and 25°C, rather higher than the 45°C current HPC racks can tolerate. But they can't get steamed up, because humidity needs to stay between 25 and 60 percent "to prevent condensation on chilled components.""
The Open Compute Project (OCP) initiated a workstream to develop guidance for deploying quantum computers alongside classical high-performance systems in datacenters. The effort will collect operational experiences and produce open specifications, best practices, and checklists covering cryogenic cooling, environmental controls, and hybrid scheduling and orchestration. A 20-qubit superconducting system at LRZ showed quantum machines have more stringent but manageable environmental constraints and require extra redundant infrastructure because outages can cause about ten days of downtime for recalibration. Power consumption is typically lower than other HPC rigs. Cryostats weigh hundreds of kilograms, demanding floor loads near 1000 kg/m². Liquid cooling needs water at 15°C–25°C and humidity between 25–60%; lighting and magnetic-field limits also apply.
