A South Korean analysis workforce has efficiently and independently developed a key element for quantum computer systems, a future strategic know-how. The whole course of, from chip design and fabrication to packaging and efficiency evaluation, was carried out utilizing Sungkyunkwan University’s proprietary know-how.
Sungkyunkwan University introduced on the twenty fifth {that a} workforce led by Professor Jeong Yeon-wook of the Department of Quantum Information Engineering has independently developed the Traveling-Wave Parametric Amplifier (TWPA), a core element for quantum computer systems and an export-controlled merchandise. Samples are at present being distributed to researchers in Korea and overseas for efficiency verification.
Quantum computer systems can resolve sure sorts of issues which are virtually unimaginable for classical computer systems (together with supercomputers) because of the in depth calculation time required. The problem lies in stably implementing numerous ‘qubits,’ the fundamental unit of quantum info that makes use of the quantum states of matter. Qubits can take numerous bodily types, corresponding to superconducting digital circuits, atoms, or ions.
Among these, superconducting circuit-based quantum computer systems are thought of a number one method, primarily adopted by international tech giants like Google and IBM.
The quantum alerts generated by qubits are extraordinarily faint, requiring a exact sign amplifier to learn them with out errors. The TWPA is a vital part for the operation of quantum computer systems, because it amplifies alerts with virtually no added noise.
Leading nations in quantum know-how, together with the United States, Europe, Canada, and the United Kingdom, have been implementing express export controls on quantum applied sciences and pc parts since 2024. The TWPA is a primary instance of an export-controlled merchandise, labeled as a strategic materials on account of its excessive technical issue, with just a few nations possessing the know-how to supply it.

The Sungkyunkwan University analysis workforce has achieved world-class efficiency with their TWPA when it comes to amplification acquire, frequency bandwidth, and loss charge, securing all the cycle of know-how from mass manufacturing to packaging with their very own know-how.
Kim Yeong-doo, a researcher at Sungkyunkwan University who led the examine, acknowledged, “This is the result of years of consistent research and development in chip processing and cryogenic microwave packaging for superconducting qubits and quantum processing units (QPUs).” He added, “The rapid progress from design to chip fabrication showcases Sungkyunkwan University’s capabilities as well as Korea’s accumulated semiconductor technology.”
Professor Jeong stated, “This achievement is a turning point for Korea’s quantum materials, components, and equipment sector. It’s significant because we have secured core quantum computer component technology at a time when quantum technology is rapidly industrializing; we have developed the entire state-of-the-art quantum chip process with purely domestic technology to counter export controls on strategic components; and we have secured the yield and mass-producibility for commercialization.”
The analysis workforce plans to commercialize this R&D achievement by means of know-how switch to business or by launching a startup.
