SEOUL, September 10, 2026 — Quantum Expo Korea 2026 is underway at COEX in Seoul from September 9 to 11, bringing together companies working across quantum computing, cybersecurity, cryogenic technology, control systems, software and related infrastructure.
A walk through the exhibition floor today showed that quantum technology is gradually moving beyond the research laboratory and beginning to develop into a broader industrial ecosystem.
One of the most visible exhibits was Quantinuum, where the Helios quantum computing platform provided visitors with a closer look at how next-generation quantum systems are being developed and presented as practical computing infrastructure.
Thales highlighted security technologies for the post-quantum era, reflecting another important side of the industry: organizations may need to prepare their cybersecurity infrastructure for quantum-era threats even before large-scale quantum computers become commercially widespread.
Korean company SDT also demonstrated equipment related to quantum system design and cryogenic infrastructure. Its display was a useful reminder that the quantum industry is not only about qubits. Cryogenic cooling, vacuum systems, precision control, RF, optics, sensors and software will all become part of the supply chain required to operate future quantum computers.
AI and conventional computing infrastructure were also visible around the exhibition area, suggesting that the future may not be a simple competition between classical and quantum computing. Instead, hybrid architectures combining CPUs, GPUs and quantum processors are likely to become increasingly important.
The quantum market remains at an early stage, but the industrial structure around it is becoming clearer. For Korea, opportunities may extend far beyond developing quantum processors themselves. The country’s existing strengths in semiconductors, electronics, precision manufacturing, communications and data center infrastructure could also become part of the emerging quantum supply chain.
Quantum Expo Korea 2026 offers an early glimpse of how the next generation of computing infrastructure is beginning to take shape.
