Oxford Quantum Circuits (OQC) announced on July 5, 2022, that it had raised £38 million—about $46.45 million, commonly rounded to $47 million—in the first close of an ongoing Series A. The round was co-led by Lansdowne Partners and UTEC, with participation from British Patient Capital, Oxford Science Enterprises and Oxford Investment Consultants.
The funding was aimed at scaling OQC’s superconducting quantum hardware, expanding into Asia-Pacific—particularly Japan—and developing private quantum-computing-as-a-service (QCaaS). It was an important financing milestone, but it was not proof that general-purpose commercial quantum computing had arrived, nor is it OQC’s latest funding event.

What OQC raised—and what “$47 million” means
OQC’s official announcement described the transaction as a £38 million first close of an ongoing Series A. The company gave an approximate dollar equivalent of $46.45 million; contemporaneous coverage rounded that figure to $47 million. The dollar amount was therefore a conversion, not a separately raised $47 million tranche.

A first close means investors committed capital at an initial closing while the financing could remain open for additional commitments. It is more precise to say OQC announced a £38 million first close than to imply that £38 million was necessarily the final Series A total.
#1 Best Overall
OQC said the financing was the largest-ever Series A for a UK quantum-computing startup at the time. That is a company or contemporaneous-market characterization, not an independent measure of technical performance.
OQC’s announcement identified the round’s co-leads and participating investors.
Who invested?
- Lansdowne Partners and UTEC—The University of Tokyo Edge Capital Partners co-led the round.
- British Patient Capital, Oxford Science Enterprises and Oxford Investment Consultants also participated.
The investor mix reflected the financing thesis: develop UK-originated quantum hardware, build a commercial service around it, and expand internationally. UTEC’s involvement was especially consistent with OQC’s stated interest in Japan and the wider Asia-Pacific market. British Patient Capital’s later disclosure confirms that it invested £7 million in OQC’s 2022 Series A.

Oxford Quantum Circuits is a UK quantum-computing company spun out of Oxford-related research. Its focus is superconducting quantum processors and cloud-delivered access to those systems. Later University of Oxford coverage describes OQC as a spinout of the Department of Physics and a provider of quantum-compute-as-a-service.
OQC’s hardware architecture was called Coaxmon, which the company and contemporaneous coverage described as a patented three-dimensional processor architecture based on superconducting quantum technology. The Series A was intended to support research and development, scale quantum systems and expand the company’s service infrastructure.
What does QaaS mean?
“QaaS” is shorthand for quantum computing as a service. QCaaS is the more precise term because it distinguishes the offering from generic cloud software.
Under this model, a customer does not buy, cool and operate a quantum computer. Instead, the customer typically:

- Sends the workload to a simulator or quantum processing unit (QPU).
- Runs the circuit, often many times or “shots,” because quantum measurements are probabilistic.
- Receives measurement results through the cloud service.
This model reduces the capital and engineering burden of owning a machine. It can give researchers, developers and enterprises access to specialized hardware through infrastructure they already use. The trade-off is that users depend on provider availability, device queues, regional access, usage charges, hardware noise and the provider’s software stack.
QCaaS improves access; it does not by itself solve high error rates, limited circuit depth, difficult algorithm design or the absence of demonstrated quantum advantage for most commercial workloads.
What was OQC selling?
The 2022 financing centered on two connected assets:
- Quantum hardware: superconducting processors using OQC’s Coaxmon architecture.
- Private QCaaS: controlled cloud access to OQC systems for organizations that may need more predictable scheduling, workload isolation or support than a shared public service offers.
At the time, OQC systems were available through OQC’s private cloud and through Amazon Braket. The public-cloud route provided distribution beyond a laboratory or direct sales relationship, while the private offering positioned OQC for more controlled enterprise engagements.

Public cloud versus private access
| Model | Potential advantages | Important limitations |
|---|---|---|
| Public cloud | Lower entry barrier, pay-as-you-go experimentation, existing cloud integration and access to multiple hardware providers. | Queues, shared availability, separate cloud costs and less control over scheduling or isolation. |
| Private or dedicated access | More predictable scheduling, potentially stronger workload isolation and direct enterprise support. | Greater commercial complexity, potentially larger commitments and no automatic improvement in hardware performance. |
Private access also does not guarantee better results. A dedicated customer still faces the underlying limitations of noisy quantum hardware and immature algorithms.
Rank #3
What was available in 2022?
In February 2022, OQC’s Lucy system became publicly available through Amazon Braket. AWS described Lucy as an eight-qubit superconducting QPU and the first publicly available OQC QPU on Braket. AWS also described the launch as expanding Braket into the London region. See AWS’s launch announcement.
Eight qubits is a concrete hardware specification, not a verdict on usefulness. Evaluating a QPU also requires considering gate fidelity, connectivity, coherence, error rates, calibration stability, circuit depth, queue time and the workload being run. A smaller processor with better fidelity may be more useful for a particular circuit than a larger but noisier device.
Likewise, language such as “commercially viable” should be attributed to OQC or its contemporaneous materials unless supported by independent customer, revenue or benchmark evidence. Hardware availability is not the same as production readiness or economic advantage over classical computing.
Why Japan and Asia-Pacific mattered
OQC said the financing would support expansion into Asia-Pacific, with Japan a particular target. The company’s stated rationale was that Japan has substantial technology and financial-services sectors and could be an important market for early quantum experimentation.
That strategy should not be confused with proof that Japanese customers had already achieved commercial quantum advantage. In 2022, the more defensible interpretation was that OQC was seeking enterprise, financial-services, industrial and research demand in a strategically important region.
How investors should interpret the business model
The Series A was principally a bet on turning capital-intensive quantum hardware into an accessible service. That model has several potential advantages:
Rank #4
- Distribution: Cloud access can put a processor in front of more developers and researchers.
- Recurring service potential: Customers may pay for usage, reservations, support or dedicated capacity rather than purchasing a machine outright.
- Lower customer friction: Organizations can experiment without building cryogenic and control systems.
- International reach: Cloud infrastructure and regional expansion can broaden access beyond the company’s home market.
But the model also carries substantial execution risk. Superconducting systems require specialized fabrication, cryogenics, control electronics, engineering and continuing error-reduction research. A successful funding round supplies resources; it does not establish that customer revenue, utilization or margins have reached scale.
The practical costs and risks of using QCaaS
Anyone evaluating a cloud quantum service should separate the price of a QPU run from the full cost of an experiment. Depending on the provider and device, costs can include:
- Per-task and per-shot QPU charges.
- Hourly reservations or dedicated capacity.
- Simulator, notebook and hybrid-compute charges.
- Classical processing, storage and data-transfer costs.
- Repeated runs needed to obtain statistically useful results.
Amazon Braket’s pricing page lists usage-based and reservation pricing that varies by device. AWS also documents spending limits and cost tracking in its cost-management guidance, while noting that limits do not cover every associated simulator, notebook, hybrid-job or reservation charge.
Commercial and technical due diligence should also check:
- Whether the device is available in the required cloud region and on the relevant date.
- Expected queue times and reservation rules.
- Whether sensitive data can be sent to the provider under the applicable data-processing terms.
- How results compare with a strong classical baseline.
- Whether the workload is deep or large enough to be dominated by hardware noise.
- Whether the demonstration is a simulator result, a QPU result, a research proof of concept or a production deployment.
What happened after the Series A?
The £38 million announcement should now be read as an early financing milestone, not OQC’s current funding position.

What the 2022 deal did—and did not—prove
The financing demonstrated that investors were willing to fund a UK company pursuing a hardware-plus-cloud strategy in quantum computing. It also gave OQC capital to develop processors, establish private access and pursue international markets.
It did not prove that OQC had achieved fault-tolerant quantum computing, that its systems would outperform classical computers on broad business workloads, or that customers had reached a commercially meaningful quantum advantage. Nor does a qubit count alone answer those questions.
For investors and technology buyers, the useful distinction is between access and value. A cloud service can make a QPU available. Demonstrating value requires a reproducible workload, appropriate metrics, a credible classical comparison and economics that justify the operational complexity.

Bottom line
OQC’s “$47 million Series A” refers to its July 2022 announcement of a £38 million first close, co-led by Lansdowne Partners and UTEC. The money supported superconducting hardware, the Coaxmon architecture, private QCaaS and Asia-Pacific expansion.
The strategic idea was straightforward: customers should access quantum hardware through the cloud rather than own and operate a cryogenic machine. Whether that becomes a durable business depends on hardware performance, utilization, customer demand and measurable advantages on real workloads—not on the fundraising figure alone. Since then, OQC has announced substantially larger financings, including a $100 million Series B and a £260 million Series C, so the 2022 round is best understood as an early milestone in a continuing company story.
