KT SAT Showcases World’s First Satellite-5G Router Connectivity

– Korea’s Sole Satellite Operator to Lead Global Satellite Industry with 5G –

– KT SAT Also Demonstrated New Broadcasting Services with KT Skylife –

SEOUL, South Korea, Oct. 1, 2020 — KT SAT Co, the satellite-operating subsidiary of KT Corporation, South Korea’s largest telecommunications company, demonstrated the world’s first satellite-5G hybrid router transmission technology at the SatelliteAsia 2020 exposition.

The cutting-edge technology for seamless connectivity between satellite and 5G is jointly developed by the KT Institute of Convergence Technology last November. KT SAT presentations at the global expo are also highlighting the possibility of using satellites as communication backup networks and extending their use to broadcast communication.

KT SAT hopes to gain momentum in consolidating its position as a leading global satellite operator by showcasing its satellite resources and technology during the event. South Korea’s sole satellite operator aims to secure a beachhead for its global outreach and expand its communication satellite business segment.

"Our participation in the SatelliteAsia online exposition this year opens a new page in global communication in a COVID-19 world," KT SAT CEO Song Kyung-Min said. "In the years ahead, we at KT SAT will show our satellite technology prowess and enhance our status in the global market."

SatelliteAsia is held annually as a part of ConnecTechAsia, the largest broadcast communication exposition in the Asia-Pacific region. KT SAT has been participating in the exposition, held in Singapore, since 2014. Because of the COVID-19 pandemic, this year’s global gathering of major satellite operators is held online from September 29 to October 1.

As a powerhouse of 5G and broadcast, a current key issue in the industry, KT SAT’s online booth at the expo is displaying a variety of contents on its satellite technology and services besides its technology for connecting satellite and other networks. The company also actively utilizes the SatelliteAsia conference and booth displays. Visitors may engage in a real-time Q&A session with KT SAT officials.

KT SAT officials are also participating in a forum at the online expo, which explores the next phase of satellite data market in Southeast Asia, and are engaging in panel discussions with global satellite operators.

The panels are devoted to changes and trends in the satellite data market, sustainable growth of mobile backhaul via satellite and solution development in the broadband services market. The participants share their experiences and pursue new opportunities.

KT SAT is also exhibiting its latest broadcast communication services in collaboration with KT Skylife Co., another KT subsidiary and provider of satellite broadcasting services. The exhibition emphasizes the synergy from collaboration between KT’s two major satellite units.

The exhibits focus on KT Skylife’s successful introduction of an android-based set-top box and changes in the market for Direct-to-Home (DTH) service based on High Efficiency Video Coding (HEVC), a video compression standard doubling the compression ratio of H.264/AVC and supporting 8K ultra-high definition.

IQM staff publishes a quantum-computer breakthrough in Nature


The new high-speed nanoscale radiation detector is now on par with the best quantum computer readers. Many present IQM employees co-authored the research carried out at Aalto University and VTT Technical Research Centre of Finland.

ESPOO, Finland, Oct. 1, 2020 — Prof. Mikko Möttönen‘s university research group and collaborators have engineered a fast and ultra-sensitive nanoscale bolometer that detects very faint microwave radiation. In fact, the radiation detected is so weak that heating up a cup of coffee at room temperature, for 1°C in a microwave oven would have taken 50 septillion times more energy. That is a 5 followed by 25 zeroes.

"The device is so tiny; it could even fit inside a bacterium," says Möttönen who is a joint Professor of Quantum Technology at Aalto University and VTT, and also a Co-Founder of IQM.

The new bolometer can measure the energy of photons much more accurately and faster than before. This is essential for quantum computers, since measuring the energy of qubits, the quantum bits, is an integral part of quantum algorithms. Moreover, the device is small and readily integrable into superconducting quantum processors, providing a clear path towards real-world applications.

"We started the proof-of-concept using gold palladium for the bolometer," says M.Sc. Roope Kokkoniemi, the first author of the Nature paper who just joined IQM. "It worked but at the same time we also figured out how to make it even better. This is where graphene comes in as a replacement. The end result is indeed a much better sensor that can operate at higher speed, so much better that it can be useful in reading out the state of a superconducting qubit, the building block of a superconducting quantum processor," added Roope. This has also been a collaborative effort with Professor Pertti Hakonen‘s NANO group of Aalto University, with VTT, and with National University of Singapore.

Accelerating the development at IQM
In quantum computers such as the ones developed at IQM, this detector technology could prove very useful in replacing conventional readers and enabling the scaling up of future quantum processors due to its relatively small size. By virtue of being at the epicenter of quantum in Finland, IQM is in a unique position to commercialize such breakthroughs through close cooperation with the growing local quantum ecosystem.

"We consider this an exciting milestone in the field of quantum technology. IQM is constantly looking for new ways to enhance its quantum-computer technology and this new bolometer certainly fits the bill," explains Dr Kuan Yen Tan, Co-Founder of IQM who was also involved in the reported research.

Technology from the best research
IQM is a prime example of a successful technology transfer story, epitomizing how research can be commercialized in an expedited way. IQM has become the leading quantum-computer company in Europe in an extraordinarily short time, already making its way towards the first commercial quantum computer sale. The company has managed to establish itself a unique foundation in the field, not only because of it has been able to recruit a major fraction of the highly limited pool of talented quantum engineers, but also because of its ability to cooperate with universities and industry partners all over Europe.

Significant part of IQM’s rapid development and brilliance in the field of quantum computing stems from the close interplay with academia. In fact, IQM is highly integrated in academia and most of its employees have research background. IQM’s team has collectively published over 640 scientific articles with more than 27,000 citations.

IQM’s aim is to become a pan-European quantum-computer company and further expand its partnerships with the best research teams all over Europe.
