TL;DR — The Answer: Diraq silicon spin quantum computer explained in one line: on 9 November 2026, Australian company Diraq switched on an 8-qubit silicon spin quantum computer inside Equinix's commercial data centre in Sydney — the first silicon spin system, Diraq says, to run in a shared commercial facility. It is a deployment proof point, not a useful computer yet: no performance benchmarks have been published for it, and Diraq's target is 256 qubits in the same system within a year.
📌 Key Highlights
- Live on 9 November 2026: Diraq's silicon spin quantum computer is now running at Equinix in Sydney, Australia — the deployment was announced as a plan on 1 September 2026 and is now installed and live.
- 8 qubits today, 256 targeted: the system currently operates with eight qubits, and Diraq says it is targeting up to 256 qubits in the same deployed system within the next year.
- Small and light on power: the whole system draws less than 20 kW and takes 170 square feet of floor space, with its cryogenic cooling and control electronics self-contained.
- Built like ordinary chips: the qubits are made with the same CMOS semiconductor processes as conventional processors, so scaling means swapping the quantum processor, not rebuilding the data centre around it.
- The "world's first" is Diraq's claim: no outside party has independently verified the first, and no error rates, coherence times or benchmarks for the deployed system have been published.
What happened?
On 9 November 2026, Diraq announced that it has installed its quantum computer inside a commercial data centre — live at Equinix (Nasdaq: EQIX) in Sydney, Australia. The announcement, carried by GlobeNewswire, says the system is the world's first silicon spin quantum computer to operate inside a commercial data centre, and Australia's first quantum computer in a commercial data centre of any kind.
This is the second half of a story that started on 1 September 2026, when Diraq and Equinix announced the plan: an 8-qubit silicon chip with all its cryogenic cooling and control electronics self-contained, installed alongside standard servers, with installation on track to finish in October 2026. The 9 November announcement confirms the installation is done and the system is live.
"We are now at a point where quantum computing can start to reach industries and the people they serve," said Andrew Dzurak, Diraq's CEO and founder. "Our silicon spin approach is what puts that within reach in five years, not decades. It gives us a manufacturing path already proven at industrial scale, a cost curve that improves as we add qubits, and a system designed to run inside today's existing computing infrastructure."
Equinix's Harmeen Mehta, Executive Vice President and Chief Digital and Innovation Officer, added: "The next chapter of computing won't be defined by AI, cloud or quantum in isolation, but by how these technologies work together. Diraq's deployment in our data center is an important proof point for quantum, demonstrating a path for these systems to operate alongside the digital infrastructure enterprises already rely on."
Alongside the deployment, Diraq launched Quantum at Work, a report on what future utility-scale quantum computers could do in medicine, energy, materials, climate and transport.
Diraq silicon spin quantum computer explained: how silicon spin qubits work
A silicon spin qubit stores quantum information in the spin of a single electron — think of spin as a tiny compass needle that points up or down, giving the 0 and 1 of the qubit, with superpositions of both in between. The electron is trapped in a quantum dot, a nanoscale electrical cage roughly 50 nanometres across, formed by applying precise voltages to metal gates patterned on a silicon chip.
Two things make this approach different from the superconducting qubits used by IBM and Google. First, size: a quantum dot is about 50 nanometres across, while a superconducting transmon resonator is roughly 100 to 200 micrometres — about 4,000 times larger in linear dimension — which is why silicon spin qubits are, in theory, packable by the millions onto a single chip. Second, manufacturing: the dots are built with standard CMOS processes on 300 mm wafers, the same production lines that make ordinary processors, instead of custom fabrication.
The physics has been validated in the lab. In September 2025, Diraq and imec reported in Nature that silicon spin qubits fabricated on an industrial 300 mm line achieved single- and two-qubit fidelities above 99 percent, past the threshold quantum error correction needs. In July 2026, the pair reported an eight-qubit silicon spin array built on a 300 mm CMOS line, published in Nature Communications — the same qubit count as the system now sitting in Sydney. Research elsewhere is pushing the same technology forward: RIKEN demonstrated simultaneous control of silicon qubits earlier this month. Silicon spin qubits also run warmer than superconducting ones, at around 1 kelvin rather than the millikelvin range, though they still need serious cooling: the Equinix system's cryogenics are built in.
Single-qubit operations are done with microwave pulses that rotate the electron's spin; two-qubit operations use the exchange interaction, briefly lowering the barrier between neighbouring dots so the electrons interact. The material is isotopically purified silicon-28, which strips out the magnetic isotopes in natural silicon that would disturb the qubit.

Why a data centre matters more than the qubit count
Eight qubits cannot do anything useful — that is not the point of this deployment, and Diraq does not claim otherwise. The point is where the machine sits. Until now, quantum computers have lived in research labs, surrounded by custom infrastructure. A system running inside a commercial data centre, next to the servers that run banking, healthcare and retail workloads, is a test of whether quantum hardware can behave like ordinary enterprise infrastructure: installed by the data centre's own processes, powered from its existing supply, and scaled by swapping a chip rather than rebuilding a room.
The power and footprint numbers are the argument. At under 20 kW, the current system draws less than a single rack of high-end AI servers; Diraq expects even a future utility-scale system to draw around 300 kW, which it says is less than a third of the power demanded by one next-generation AI rack. If those numbers hold as qubit counts rise, the cost of housing quantum computers falls dramatically compared with technologies that need ever-larger dilution refrigerators and wiring looms.
There is institutional backing behind the claim, too. Diraq recently advanced to Stage C of DARPA's Quantum Benchmarking Initiative — one of just six companies to reach the programme's final stage, with potential funding of up to US$300 million — and signed a US$38 million letter of intent with the US Department of Commerce under the CHIPS and Science Act, the only company focused on silicon spin qubits in that funding round. Note both are potential, not awarded: Stage C funding is "potential", and a letter of intent is not a grant.
Why it matters for India readers
India has no Diraq presence and no direct stake in this deployment, but the approach is directly relevant to India's quantum and semiconductor plans. India approved its National Quantum Mission in 2023, with a budget of about ₹6,003 crore running to 2030-31, and is simultaneously building a domestic semiconductor ecosystem, including chip fabrication and assembly projects. A quantum technology that runs on the same CMOS processes as ordinary chips — and slots into existing data centres rather than demanding bespoke facilities — fits both of those programmes far more naturally than a technology that needs its own supply chain and its own buildings.
For Indian readers following quantum computing, the honest framing is this: the race is no longer only about who has the most qubits. IBM and Google lead on qubit counts by a wide margin, but their machines live in labs — NVIDIA's JUPITER 104-qubit quantum simulation shows how much classical hardware is still needed to model quantum systems. Diraq is betting that the winner will be whoever can manufacture qubits like chips and deploy them like servers — and this Sydney installation is the first real-world test of that bet. The next proof point, by Diraq's own timeline, is the jump to 256 qubits in the same system within a year.

FAQs
What is a silicon spin quantum computer?
A quantum computer that stores information in the spin of single electrons trapped in nanoscale structures called quantum dots on silicon chips. Unlike superconducting quantum computers from IBM or Google, silicon spin qubits are built with the same CMOS semiconductor processes used to make ordinary chips, which is why Diraq argues they can be manufactured at scale.
How many qubits does Diraq's quantum computer have?
The system deployed at Equinix Sydney has 8 physical qubits. Diraq says it is targeting up to 256 qubits in the same deployed system within the next year. For comparison, Diraq's roadmap aims for a first commercial product with thousands of physical qubits in the first half of 2029.
Why does it matter that a quantum computer is inside a data centre?
Because it tests whether quantum hardware can operate as ordinary enterprise infrastructure. The Diraq system sits alongside standard servers, draws under 20 kW, takes 170 square feet, and can be scaled by replacing its quantum processor chip rather than rebuilding the facility — all things that matter far more to a buyer than a qubit count in a lab.
When will Diraq's quantum computers be useful?
Not yet. The 8-qubit deployment is a proof point for the deployment model, with no published performance benchmarks. Diraq's own roadmap targets a commercial product with thousands of physical qubits in the first half of 2029, and its white paper targets 150,000 physical qubits by 2029 — both are company targets, not demonstrated results.
Takeaway
Diraq has put a quantum computer where the customers are — inside a commercial data centre, running on chip-factory technology. The machine itself is tiny and unproven, but the deployment model is the story: if silicon spin qubits scale the way Diraq claims, quantum computing stops being a lab curiosity and starts being a data-centre appliance. The 256-qubit upgrade, due within a year, is the next thing to watch.
