"Meet the Next Generation of Quantum Technology"

Date: April 17, 2026 – August 23, 2026Venue: Special Exhibition Hall, Gwacheon National Science Museum

SDT, one of Korea’s leading quantum technology companies, joined the journey in preparing Quantum Generation, the Gwacheon National Science Museum’s 2026 brand exhibition.

Following the spirit of last year’s International Year of Quantum, which marked the 100th anniversary of quantum mechanics, this exhibition shows that quantum technology is no longer confined to the laboratory. It is becoming part of the world the next generation will live in. At this exhibition, SDT helped present the culmination of Korea’s homegrown quantum computer technology, bringing the world of quantum closer than ever to the public and to young visitors.

Three Years of Preparation, and the Journey of Quantum Technology into the Exhibition Hall

The Gwacheon National Science Museum’s brand exhibitions are not simply permanent displays. Quantum Generation is also the result of three years of planning and collaboration by many people at the museum, and SDT considers it meaningful to have been able to take part in that journey.

Quantum technology is built on the principles of superposition and entanglement, concepts that cannot be seen with the naked eye. For that reason, it is also one of the most challenging subjects to bring into an exhibition format. To address this, SDT worked closely with the Gwacheon National Science Museum to explore how to present not abstract concepts, but quantum technology in real operation, in a way that visitors could directly experience and understand.

KREO SC-20: Korea’s Homegrown Quantum Computer

The exhibit shown below is a model from KREO, SDT’s full-stack quantum computer series. Built with Korean-developed technology across the entire stack—from quantum system architecture and control hardware to system integration and operating software—KREO is a homegrown quantum computer series. It is also the first commercially available open-access superconducting quantum computer in Korea currently in operation on Dosan-daero in Gangnam-gu, Seoul.

KREO SC-20 is a 20-qubit superconducting quantum computer, powered by the organic integration of the following components:

• 20-qubit superconducting Quantum Processing Unit (QPU)

• SDT’s QCU (Qubit Controller Unit), the qubit control hardware

• CryoRack, a dilution refrigerator that creates an ultra-low-temperature environment

• A quantum–AI hybrid system connected through NVIDIA DGX B200 GPUs and NVQLink
  
  

QCU (Qubit Controller Unit): Qubit Control Hardware

If the QPU is the brain of a quantum computer, then the QCU (Qubit Controller Unit) is the device that sends precise signals to that brain and reads them back. The QCU is qubit control hardware that generates, analyzes, and measures high-frequency signals. It is used to control qubits not only in superconducting quantum computers, but also in systems based on neutral atoms, diamond NV centers, and silicon spins.

In Korea’s quantum research environment, which long relied on imported equipment, SDT developed its QCU based on its own patented technology. With competitive pricing, fast delivery, and close technical support, the QCU has established itself as a Korean-made standard device within reach of domestic quantum researchers.

In this exhibition, visitors will be able to see this equipment up close—something that would normally only be found deep inside a research lab—and gain a more tangible sense of what kinds of hardware are required to operate a quantum computer.

Dilution Unit: The System That Creates a World Colder Than Outer Space

Superconducting quantum computers require qubits to operate in an ultra-low-temperature environment of around 10 mK (millikelvin), close to -273°C. This is a world far colder than the background temperature of outer space. The system that creates and maintains this condition is the dilution refrigerator, and at the heart of it is the Dilution Unit.

The Dilution Unit is a precision-engineered component that achieves ultra-low temperatures through the mixing and separation of two helium isotopes, helium-3 and helium-4. It consists of the Still Pot, Continuous Heat Exchanger, Step Heat Exchanger, and Mixing Chamber.

By designing and manufacturing this critical component domestically—one that had previously depended entirely on imports—SDT has marked an important milestone in the localization of Korea’s quantum cooling infrastructure.

The People Bringing Theory into Reality

SDT CEO Yoon Jiwon, in an interview for Quantum Generation, remarked, “If the past 100 years were an era of discovering and proving the mysterious theory of quantum mechanics, then the next 100 years will be an era of engineering—one in which that theory is used to solve humanity’s most difficult challenges.” He also emphasized that while “absolute zero” may appear in theory as nothing more than a number in an equation, bringing it into reality requires solving for hundreds or even thousands of precision components, thermodynamic challenges beyond the textbook, and tightly interwoven global supply chains.

The KREO SC-20 and its component systems on display in Quantum Generation stand as a record of that very journey—from theory to reality—made possible through Korean technology. For visitors who may still feel an abstract sense of distance or uncertainty toward quantum technology, we hope this exhibition serves as a marker of how modern engineering can bring such ideas into the real world.

A Message to the Next Generation

The exhibition title, Quantum Generation, is more than a simple phrase. By the time the elementary school students visiting this exhibition enter university and begin their careers, quantum technology will likely have become naturally embedded in many parts of everyday life, much as artificial intelligence has. They are the very generation who will live in that era: the Quantum Generation.

As a company that designs and manufactures Korea’s quantum ecosystem, SDT wanted to show the next generation that quantum technology—still often regarded as an abstract concept—is not only already before our eyes, but will soon become a major pillar of Korean industry. Encountering quantum for the first time not through complex equations, but through real equipment in front of them, may become a science lesson that stays with young visitors for a long time. SDT considers it deeply meaningful to be part of that first encounter.

The Quantum Generation exhibition will be on view at the Special Exhibition Hall of the Gwacheon National Science Museum for approximately four months, from April 17 to August 23, 2026.

Visitors of all ages are welcome, and children of elementary school age or younger are encouraged to attend with a guardian.

SDT will continue working to bring Korean quantum technology closer to everyday life.
