COMPANY PROFILE / QUANTUM COMPUTING

Diraq
An Australian company turning silicon transistors into qubits, in the same fabs that make PC chips

Quantum computers are often assumed to need special circuits and exotic equipment. Diraq takes the opposite view. It uses the equipment and processes of the semiconductor factories that make smartphone and PC chips, and treats the direction of a single electron, trapped in a tiny piece of silicon, as a qubit (the basic unit of quantum computation). On 7 October 2026 it was named by the U.S. Defense Advanced Research Projects Agency (DARPA) as one of the companies moving to Stage C, the final stage of DARPA’s evaluation program. Yet the largest chip it has shown working has only eight qubits, a long way from its targets of hundreds of thousands to millions. This profile explains what it builds, who it works with and what it is aiming for, using only primary sources we could check, and in terms a reader new to quantum computing can follow.

Sources: Diraq’s website and press releases, papers in Nature, and DARPA’s public pages, used as primary material (the company is private, so there are no securities filings). Date checked: 16 October 2026.

WHAT RUNS TODAYAn 8-qubit arrayPhysical qubits, made on imec’s 300 mm line (July 2026)
DARPA QBIStage CThe final stage, announced by DARPA on 7 October 2026
COMPANY TARGET150,000 physical and up to
1,000 logical qubits (2029)
A company target, not an achievement
The one point to grasp first

Quantum computing companies differ mainly in what they use to make a qubit. Diraq chose silicon: the same material as the CPUs in PCs, which factories around the world already machine with extreme precision. Diraq’s main claim is that its qubits can be made as they are in existing semiconductor fabs Sourced. The current gap is quantity, by orders of magnitude. The largest array disclosed is eight qubits, and the company’s 2029 target of 150,000 physical qubits is about 19,000 times larger Our calculation (150,000 / 8 = 18,750).

Three terms to learn first

Qubit (quantum bit): the basic unit of a quantum computer, which uses a superposition of 0 and 1. In Diraq’s design, a qubit is the “spin” of one electron trapped in silicon (a compass-needle-like orientation, up or down), with up and down standing for 0 and 1.

Physical and logical qubits: a physical qubit is one piece of hardware and is sensitive to noise; a logical qubit bundles many physical qubits so that errors can be found and fixed. When you read a number, always check which one it counts.

Fidelity: how accurate an operation is, as a percentage. At 99%, about one operation in a hundred goes wrong. What was measured (a single-qubit operation, a two-qubit operation or readout) changes the meaning, so this article always states the conditions. For more, see our explainer on coherence and fidelity.

2. The logo and how the name is written

A note on names: the company is Diraq (written in lower case, “diraq”, in its logo). The primary sources we checked do not explain where the name comes from, and we could not confirm the company’s full registered legal name.

Official site: https://diraq.com/ (the logo was taken from the image used in the site header)

3. Where the company sits in quantum computing

Quantum computing companies have different strengths and challenges depending on what they use to make a qubit. The figure below sorts the companies in this series into four types. Diraq falls in the third type, “photonic, silicon and other approaches”, as a silicon company.

Four types of companies in quantum computing The same "quantum company" label hides different strengths and challenges, depending on how qubits are built Superconducting Qubits made from circuits IBM / Google Rigetti / IQM Manufacturing know-how Cooling and wiring Trapped ions & neutral atoms Trapped atoms and ions Quantinuum / IonQ QuEra / Pasqal High precision, control Scaling and speed Photonic, silicon & other approaches Light or silicon qubits PsiQuantum / Xanadu Diraq / Microsoft Photonics and scale Approach still unproven Software, cloud & ecosystem Cloud, software, comms NVIDIA / AWS Fujitsu / Toshiba Ease of use, links Own devices not the focus Diraq is in the photonic/silicon group, as silicon: one electron’s spin is the qubit, made in a fab The largest array running is eight physical qubits, far from the target of about 150,000
Fig. 1 The four types of companies in quantum computing, and where Diraq sits. The classification is ours, and the company names are examples from those profiled in this series Our calculation. That Diraq uses the spin of electrons in silicon rests on its website and papers (References 1 and 6).

Here is each type in a sentence or two.

TypeWhat the qubit isStrengthDifficulty
SuperconductingAn electrical circuit cooled to extremely low temperatureCircuits can be made with semiconductor-style processesNeeds refrigerators and a great deal of wiring
Trapped ions and neutral atomsAtoms held in place with electric fields or lightEach one is identical, so precision is highIncreasing the number, and operating speed
Photonic, silicon and otherA particle of light (photon), the spin of an electron in silicon, and so onMay be made in semiconductor factories; photons can be linked by optical fiberThe approach is still unproven
Software, cloud and ecosystemNo qubits of its ownSupports the whole field through cloud, software and communicationsNo hardware advantage of its own

A materials engineer's view: isotopically purified silicon and the oxide interface

What decides how good a silicon qubit is, is how quiet the place where the electron sits is. Natural silicon contains a small amount of an isotope (silicon-29) that has a nuclear spin (a tiny magnet in the nucleus), and it disturbs the electron’s spin and causes errors. The 2025 Nature paper states that residual nuclear-spin-carrying isotopes contribute substantially to operational errors, and that further isotopic purification is a clear pathway to higher performance Sourced. The other factor is disorder at the interface between silicon and the oxide (insulating) layer, which causes charge noise and so errors. Diraq’s strength is in showing that these can be reproduced with standard semiconductor processes (300 mm wafers, existing transistor machining). The 2025 Nature paper reports fidelities above 99% in all four devices and answers the question of whether performance seen in academic labs carries over to a foundry Sourced. Seen through materials, the contest is whether material purity (isotopes) and interface quality can be kept uniform at factory yields.

A company target; the claimed arrival of utility scale
DARPA'S TARGET YEAR2033The date QBI is testing (DARPA)

All of these are company targets and plans, not achievements Not yet confirmed. The roadmap on the company’s website describes a first phase (2022-2025, 10 qubits), a second phase (2025-2029, 1,000 or more) and a third phase (2029 onward, 1 million or more), which is worded differently from the numbers in the white paper and the October 2026 release (lower bounds of each phase versus specific targets).

What we could not confirm

None of the following appears in the primary sources we checked Not yet confirmed.

The price, delivery date and customers for its own quantum computers / specific performance numbers for arrays larger than eight qubits / whether the LOI will lead to a final award / the full legal name / revenue and profit / the currency and breakdown of funding raised. The white paper’s “under $1 per qubit” is a company target, not a measured value.

8. What the company is aiming for in quantum computing

This section includes points the company does not state directly. They are inferences from what the primary sources show, given with their basis.

What we read from the sourcesPrimary-source basisType
The goal is a quantum computer that fits in one rack in a data centerThe website says the processing unit is the size of one server rack and compatible with standard data centers; an 8-qubit machine is planned for an Equinix data centerSourced (company statement)
The decisive ground is manufacturing cost and volume, more than raw performanceChairman McGregor says winners will be decided by manufacturing economics, and the website sets a target of under $1 per qubitInference
It will keep dividing labor with external foundries rather than build its own fabPartnerships with imec and GlobalFoundries are central, and we found no plan to build its own volume fab (U.S. production is at LOI stage)Inference
It aims to achieve error correction with external code design (Iceberg Quantum) using fewer physical qubitsThe release of 14 September 2026 describes fitting Iceberg Quantum’s “Pinnacle” design, which uses qLDPC codes, onto Diraq’s hardware (1,000 logical qubits from 150,000 physical)Sourced (company statement)
Reaching the targets requires growth by orders of magnitudeThe largest disclosed array is eight qubits; the 2029 target is 150,000 physical qubitsInference
One inference in more detail

The white paper’s targets are 150,000 physical and up to 1,000 logical qubits in 2029, and more than 2 million physical and more than 10,000 logical qubits in 2031. Dividing gives about 150 physical qubits per logical qubit in 2029 (150,000 / 1,000) and about 200 in 2031 (2,000,000 / 10,000) Our calculation. In other words, the company expects the overhead for error correction to be 150- to 200-fold. This ratio rests on Iceberg Quantum’s code design, which the company says needs fewer physical qubits than the standard approach, the surface code Sourced. We could not confirm, however, that this code design has been run on real Diraq hardware. Demonstrating error correction on real hardware is still ahead Not yet confirmed.

The line types are our classification Our calculation; for the content and size of each tie, see the references in the text. The tie with the U.S. Department of Commerce is a letter of intent, not a final award.

10. Technologies, products and services

Diraq’s technology begins with modifying a transistor so that it traps a single electron. The next figure splits the flow into three steps.

Silicon spin qubit flow: three steps Our summary of Diraq’s description and the papers 1. Trap one electron A transistor-like structure traps exactly one electron in silicon Controlled by gate electrodes 2. Spin becomes the qubit The electron’s direction (up / down) stands for 0 and 1; use superposition Cryogenic (above 1 K shown) 3. Made in a fab Same 300 mm wafer processes as PC chips, many placed side by side Made on imec’s line Point: no new kind of factory; qubits are made with existing semiconductor processes The challenge is multiplying the number: the largest array running is 8 qubits (physical) Isotopically purified silicon and oxide-interface quality set the error size (2025 Nature paper)
Illustration The flow of Diraq’s silicon spin qubit as the company describes it (sources: website, Nature papers, imec announcements). The figure is our rendering of the company’s description Our calculation; it does not show the actual structure or dimensions of the chip.

What does it mean to make a qubit from silicon?

  1. Trap a single electron: a transistor is a part that switches an electric current on and off. Diraq applies that structure to trap exactly one electron in silicon (called a quantum dot).
  2. Make the electron’s direction (spin) the qubit: an electron behaves like a tiny magnet that points “up” or “down”. Up and down correspond to 0 and 1, and a superposition of the two is used for computation. Spin is relatively insensitive to electrical noise, which is said to help the state last longer.
  3. Mass-produce it in a semiconductor factory: the devices are made on the same 300 mm wafer processes as PC chips, so many qubits can be placed on one chip, the company says (made at imec’s fab).
  4. Cool it to operate: qubits run at very low temperature. The company describes putting control circuits (CMOS) that also work at cryogenic temperature next to the quantum chip, with room-temperature electronics connected outside. A paper has also shown operation above 1 kelvin.
A materials engineer's view: using semiconductor technology to cut cooling and wiring

Cooling and cabling are heavy burdens for a quantum computer. Diraq points toward making the control electronics themselves a CMOS chip that works at cryogenic temperature and sits next to the quantum chip Sourced. In the announcement of the Commerce LOI, GlobalFoundries describes cryo-CMOS capabilities for quantum as its own. The fact that the factory making the qubits and the factory making the control circuits belong to the same semiconductor industry is the foundation of Diraq’s case. The same announcement describes a plan for an end-to-end U.S. supply chain covering chips, cryostats and packaging, which is a future plan. Seen through materials and process, the remaining challenges are keeping qubit-to-qubit variation small over large areas and wiring density at cryogenic temperature Not yet confirmed.

Linking quantum with AI and supercomputers

Diraq works with Dell and NVIDIA on running a quantum chip and classical computers (GPUs and so on) close together. Dell is described as having placed a small HPC cluster in Diraq’s Sydney laboratory so that it can run next to a quantum processor. NVIDIA’s NVQLink is a link technology that lowers communication delay between quantum hardware and GPUs; Diraq says it uses it to achieve round trips to a GPU of about 3.3 microseconds, and to automate qubit calibration with AI models (NVIDIA Ising) (company statements) Sourced.

How to read DARPA QBI Stage C

The facts: DARPA’s Quantum Benchmarking Initiative (QBI) tests whether a utility-scale quantum computer, one whose computational value exceeds its cost, can be built by 2033. Stage A is a concept description (up to US$1 million), Stage B an evaluation of the research and development plan (up to US$15 million), and Stage C a check with a government team that the machine can be built as designed and operated as intended (up to US$300 million). On 7 October 2026 DARPA announced that Diraq, Atom Computing, IBM and IonQ had moved to Stage C (Microsoft and PsiQuantum had moved to Stage C from US2QC, the pilot program that preceded QBI) Sourced.

What to keep in mind: DARPA states that QBI is not a competition and not meant to pick winners. Reaching Stage C means being a subject of detailed verification, not a ranking of technologies or a guarantee of success. The Stage C funding is a ceiling of up to US$300 million, and Diraq’s release says US$51 million for the first year (company statement). Read it as the official page states it, without ranking the companies.
