Achieving 1,000-qubit Systems by 2032 Key to Securing Global Market Position
On March 12, the Korea Research Institute of Standards and Science (KRISS) took a significant step forward in domestic quantum computing research by demonstrating a cloud service utilizing a 20-qubit quantum computer. This demonstration was a focal point at the inaugural meeting of the Quantum Strategy Committee, established as South Korea’s national control tower for quantum research.
Choi Jae-hyeok, director of the Quantum Technology Research Institute at KRISS, noted that securing technological independence in quantum computing is crucial for supporting sovereign AI capabilities within South Korea. “The demonstration of a cloud service using a quantum computer means the commercialization of domestic quantum computers is imminent, providing the foundation for Korea to compete globally,” he stated.
Quantum computing exploits qubits’ ability to exist in multiple states simultaneously, enabling complex calculations beyond traditional computers’ reach. Despite challenges such as qubit sensitivity to external disturbances like temperature and electromagnetic interference, KRISS has identified “Quantum Linkage” as a critical technology. This method can interconnect multiple quantum computers to effectively increase qubits and computational power—a potential breakthrough for South Korea to catch up with leading countries in this field.
Choi explained that while current overseas technology limits individual quantum computers to about 1,000 qubits, Quantum Linkage could connect multiple such systems, scaling up to potentially 10,000 qubits. This strategy is seen as a hidden advantage for Korea’s rapid advancement, particularly since it was identified as promising by the U.S. Department of Energy last year.
The global quantum supply chain is expected to be established within five to ten years. Choi cautioned that slower technology acquisition would make it challenging for Korean companies to enter markets dominated by foreign entities. He urged academia, industry, and research institutes to focus their efforts around the Quantum Strategy Committee during this crucial ten-year window.
KRISS plans further development of 50-qubit and eventually 1,000-qubit quantum computers by 2032. This initiative is part of a broader national strategy leveraging quantum computing for economic growth and security advantages. As South Korea embarks on this ambitious journey, collaboration between public and private sectors will be vital for overcoming technical barriers and accelerating progress.
