Quantum SDT

The South Korean quantum technology startup SDT has completed a $20.6 million (roughly 30 billion KRW) investment round, a milestone for the global high-performance computing business. This venture, led by Praxis Capital Partners and backed by NH venture & Securities, changes how the sector hopes to create AI infrastructure.

As AI models get exponentially more complex, silicon-based data centers are approaching their processing power and energy efficiency limits. SDT aspires to overcome this constraint and create a “hybrid” paradigm that might revolutionize the global economy's digital base by directly merging quantum computing capabilities into AI infrastructures.

New Approach: AI-Quantum Hybrid

Universal quantum computers' theoretical potential and business applicability are now disconnected. Even though full-scale universal quantum computers are years away, SDT is pushing a “hybrid” technique as a short-term and long-term solution.

This method transfers complex mathematical problems like optimization and cryptography to quantum processors. A smooth integration that increases speed and decreases energy consumption without redesigning present systems is conceivable since fundamental AI workloads are still executed on traditional hardware.

SDT’s “Full-Stack” Advantage

One reason investors trust SDT is its “full-stack” capabilities. Numerous deep tech businesses focus solely on software or hardware components. In contrast, SDT integrates software, control electronics, and hardware.

Praxis Capital Partners representatives said SDT is the only Korean technology business with this much experience. SDT's delivery of Korea's first commercial quantum computer distinguishes it from other deep-tech businesses in the early stages of R&D.

Commercial momentum and aggressive financial growth

SDT is gaining commercial traction, unlike many quantum enterprises that rely on long R&D cycles without producing money. The company signed the first South Korean quantum hybrid system contract to prove its business strategy to investors and clients.

SDT's financial forecast is aggressive. The company anticipates these growth milestones:

Revenue will rise over 200% in the first half of 2026.

Annual Forecast: If contract negotiations go as anticipated, SDT expects income to rise by almost 500% annually from 2025. This expected surge is driven by AI data centers seeking a competitive edge in processing speed and energy efficiency.

Strategic IPO Path

With this cash, SDT is boosting its technology-track IPO preparations. The company hired NH Investment & Securities, an IPO underwriting expert, as its primary underwriter.

Despite not meeting profitability requirements, South Korea's “technology-track IPO” targets companies with great development prospects and technical knowledge. SDT intends to list on the stock exchange in 2026 after a technology evaluation.

Future Resource Allocation and CEO Vision

SDT CEO Jiwon Yoon believes this funding will make quantum computing part of the global digital infrastructure. Through the IPO, Yoon plans to make SDT a “global quantum company” with the funding.

The $20.6 million will go to three important sectors:

Refine Core Technology: Enhancing quantum processor error correction and stability.

Infrastructure Build-out: Stable AI-quantum hybrid environments for public and private clients.

Global Expansion: Expanding beyond South Korea into IT hotspots with high AI demand. See also Rigetti roadmap update: Cepheus-1-108Q System Launch Status.

Global and National Context

Google, IBM, and IonQ are often seen as fighting for “quantum supremacy,” but SDT's trajectory suggests that specialized, nimble hybrid application companies may be able to reach commercial viability faster. SDT claims that the “Quantum Era” will arrive by subtly integrating into data centers as infrastructure suppliers rather than experimental labs.
