Diraq, Dell Test Hybrid Quantum-Classical Computing in Sydney

Diraq and Dell Technologies have initiated testing of a hybrid quantum-classical computing setup at Diraq’s Sydney laboratory. Diraq, an Australian company specializing in silicon spin-qubit processors, is integrating its quantum hardware with a compact Dell high-performance computing cluster. This test is notable for bringing quantum hardware development into proximity with standard enterprise compute infrastructure.

Dell has deployed a small HPC cluster within Diraq’s lab, co-located with a Diraq quantum processor. This arrangement ensures close physical and network proximity between the two systems. According to both companies, the initial phase of work focuses on establishing connectivity, validating baseline latency, and executing simple test circuits across the combined system. 

Specific details regarding qubit count, circuit size, latency figures, or benchmark numbers are not available from any source, which means the results are qualitative and rely solely on the companies’ statements. No independent measurements or peer reviews of the connectivity and latency checks have been provided.

Andrew Dzurak, Diraq’s CEO and founder, articulated the objective as creating integrated systems where classical AI and CPUs handle large computations and the quantum processor engages for specific, challenging problems. John Roese, Dell Global CTO, referred to hybrid quantum-classical computing as “the term of the day.”

The Significance of the Hybrid Approach

The software aspect of hybrid workflows is already well-established. Fujitsu recently open-sourced OpenQARP, a quantum application package that integrates NVIDIA CUDA-Q for hybrid quantum-classical execution. Over 80 organizations are currently using the beta through its Quantum Simulator Challenge. Commercial demand for full-stack platforms is also evident elsewhere. 

IonQ reported record second-quarter 2026 revenue, marking a 287 percent year-over-year increase, alongside Tempo system deployments and an upward revision of its full-year guidance. These developments provide context but are not directly part of the Sydney narrative.

Silicon Qubits and Enterprise Hardware

Diraq employs modified silicon transistors to store quantum information, an approach it claims is compatible with existing semiconductor foundry processes. The company suggests this path could enable millions of qubits on a single chip, potentially fitting a utility-scale machine within a single cryogenic refrigerator.

Pairing this hardware with enterprise-grade classical computing allows Diraq to assess whether its processor can be managed using the orchestration and data-center methodologies already employed by Dell, as reported in coverage of the collaboration.

This engagement appears to be an ongoing collaboration centered around the Sydney testbed. Neither company has disclosed the contract type, duration, financial terms, or specific roadmap milestones beyond the current work. The companies have indicated that near-term efforts will include automated qubit calibration, with error correction targeted for a later stage.
