South Korea's OQT raised 14 billion won in pre-Series A funding led by DSC Investment for error-tolerant neutral-atom quantum computers, announced October 15.
Key Takeaways
- OQT closed a 14 billion won (about $10.4 million) pre-Series A round led by DSC Investment on October 15, 2026.
- Kakao Ventures and Bluepoint Partners followed on; five new investors joined. Valuation was not disclosed.
- The round follows a 3 billion won seed from February 2025 and lifts disclosed funding to 17 billion won.
Lead
OQT, a Seoul-area quantum computing startup building machines from laser-cooled neutral atoms, raised 14 billion won in a pre-Series A round announced on October 15, 2026. DSC Investment led the financing. The company said it will use the money to scale up and expand abroad while it develops error-tolerant systems built on logical qubits.
The round is nearly five times the size of OQT's seed. It comes about 20 months after that first check, which was also modest by global quantum standards.
Who Invested in the Round?
Seven investors took part. DSC Investment led, and existing backers Kakao Ventures and Bluepoint Partners made follow-on investments. Murex Partners, Stonebridge Ventures, Schmidt, Z Venture Capital (ZVC) and Global Innovation Labs (GIL) joined as new investors.
OQT did not disclose a valuation or the equity stake sold. The company also did not say how the 14 billion won splits between lead and follow-on money. Without a price, the only readable signal is the step-up in cheque size and the return of both seed investors.
What Does OQT Build?
OQT designs quantum processors in which individual neutral atoms, held and controlled by lasers, serve as qubits. Its stated target is a fault-tolerant machine that encodes logical qubits, which bundle many physical qubits so that errors can be detected and corrected. The company describes an approach it calls a software-defined quantum processor, in which hardware, software and error correction are designed together and the architecture adapts to the algorithm being run.
The founder and CEO is Kim Donggyu, a physics professor at KAIST and a founding member of QuEra, the US company known for a 256-qubit neutral-atom machine. That lineage is the company's main credential at this stage. No product, qubit count or delivery date has been announced.
Why Does the Seed-to-Pre-A Path Matter?
OQT raised 3 billion won in February 2025 from Kakao Ventures and Bluepoint Partners to build its quantum processing unit and expand research infrastructure. Both investors returning suggests the seed-stage milestones were met to their satisfaction. The company has not published those milestones, so the claim rests on the investors' behavior, not on disclosed results.
Cumulative disclosed funding now stands at 17 billion won. That is small next to the nine-figure dollar rounds that neutral-atom rivals such as QuEra and Atom Computing have raised abroad. A cheque this size buys a lab, a laser stack and a hardware team for a couple of years, not a commercial fleet. The next round will show whether OQT has moved from design to working atom arrays.
What Do the New Investors Add?
The new investor list is built around distribution as much as capital. ZVC is meant to open links to industry networks in Japan and the United States. GIL is intended to deepen technology cooperation with SRI, the research institute formerly known as Stanford Research Institute.
DSC Investment said OQT holds self-developed core quantum technology and a differentiated method that can compete globally. Kakao Ventures said the team is well placed to tackle commercialization problems in quantum computing. Both statements are endorsements of the team, not evidence of hardware performance.
How Does This Fit South Korea's Quantum Push?
South Korea has a small base of quantum hardware startups compared with the US, Europe and Japan, and venture funding for the category is thin. A 14 billion won pre-Series A led by a domestic venture firm is large for the local market, though it would be a small seed round in Silicon Valley. OQT's pitch of neutral atoms, which allow large qubit counts and lower upkeep than some alternatives, also puts it in a crowded global field where well-funded incumbents are already building error-corrected systems.
The main risk is execution speed. Neutral-atom platforms have advanced quickly, and a startup that starts late must either match the leaders' error rates or find a niche, such as regional demand from Korean research institutes and industry.
Outlook
OQT now has 17 billion won in disclosed funding, a seven-investor syndicate and cross-border ties to Japan and the United States. It has no disclosed valuation, product benchmarks or customers. The next 12 to 18 months should show whether the company can demonstrate logical-qubit operation on its own hardware and whether the investor networks convert into partnerships. A Series A would then be the first real test of how the market prices the company.
