2025 is the UN-designated International Year of Quantum, marking the industrial rise of quantum computing, sensing, and networking, with Korea advancing strategic initiatives.
The year 2025 marks a significant milestone as the United Nations designates it the International Year of Quantum Science and Technology (IYQ2025). Far beyond a ceremonial event, this initiative highlights the transition of quantum technology from theoretical research to practical applications across industries and daily life. With rapid advancements in quantum computing, sensing, and networking, countries worldwide are accelerating their national strategies. South Korea is also actively investing in policies and commercial pilot programs. This article outlines the global progress in quantum technology, Korea’s strategic response, and the ongoing efforts to engage the general public.
IYQ2025, the Year of Quantum
The United Nations officially proclaimed 2025 as the International Year of Quantum Science and Technology (IYQ2025). Spearheaded by international scientific bodies, the initiative aims to raise global awareness and understanding of quantum technologies. What was once confined to theoretical physics is now rapidly moving into real-world applications, including communication, cybersecurity, computing, and sensing.
This transition is not merely a technological shift but a reshaping of global industry, security policy, and economic strategy. Many leading countries now consider quantum innovation a key driver of national competitiveness, prompting them to design long-term development roadmaps.
Three Pillars of Quantum Technology Driving Industry
Quantum Computing: Transitioning to Practical Use
Quantum computing offers the potential to solve complex problems exponentially faster than classical computers. Companies like IBM, Google, and IonQ are racing to improve the number and stability of quantum bits (qubits).
As of 2025, IBM has successfully demonstrated its 1,121-qubit processor "Condor," moving beyond quantum supremacy into real-world problem-solving. Key application areas include molecular simulations, financial modeling, and drug discovery—fields that require high computational capacity.
Quantum Sensing: Enabling Precision at New Scales
Quantum sensors detect subtle physical phenomena such as gravity, magnetic fields, and biological signals with unprecedented precision. These sensors outperform traditional ones by an order of magnitude in sensitivity and accuracy.
Potential uses include high-precision navigation for autonomous vehicles, underground resource exploration, and neurological diagnostics through brainwave detection. As the technology matures, quantum sensing could redefine standards in medical and industrial measurement.
Quantum Networking: Redefining Secure Communications
Quantum networks enable highly secure communication channels. Quantum Key Distribution (QKD) ensures that any eavesdropping attempt renders the communication invalid, effectively making it immune to hacking.
China has already launched the world’s first satellite-based quantum communication network through the Micius project. Meanwhile, Europe is advancing intercontinental quantum network tests through the Quantum Internet Alliance. With countries like the U.S. and South Korea joining the race, the development of quantum internet infrastructure is becoming central to global digital strategy.
South Korea’s Strategic Focus on Quantum Technologies
Expanding Research and Pilot Projects
The Korean government, led by the Ministry of Science and ICT, has initiated major quantum R&D projects since 2023, particularly focused on quantum computing. Institutions such as KAIST and Seoul National University are establishing quantum information research centers and developing indigenous qubits.
Private companies like Hanwha Systems and SK Telecom are also testing quantum encryption systems. These initiatives are being piloted in Seoul, Daejeon, and Busan, forming the backbone of Korea’s quantum infrastructure.
Industry Outlook and Start-up Ecosystem Growth
Between 2025 and 2030, the government is expected to release a roadmap to drive the commercialization of quantum technology. This includes fostering startups in quantum sensing and communication devices.
The Korean Quantum Internet project is a key part of this strategy, aiming to secure early leadership in quantum network infrastructure and promote technological self-reliance.
Public Engagement and Educational Outreach
IYQ2025 includes numerous outreach programs aimed at the general public. These include exhibitions, public lectures, and interactive online content. Platforms such as YouTube and blogs are increasingly used to simplify complex quantum concepts.
Despite the field’s conceptual difficulty, engaging educational content is gaining popularity. For science communicators and content creators, this presents an opportunity to play a vital role in the public understanding of quantum technology.
Quantum Technology as a Driver of the Future
Quantum technology is no longer an abstract scientific theory but a transformative force with practical applications. IYQ2025 marks a turning point in global competition for technological leadership. South Korea, too, is stepping up its efforts through strategic planning and infrastructure investment. Mastery in quantum computing, sensing, and networking will likely become a cornerstone of national competitiveness in the years ahead.
