Expanding the Utilization of Quantum Computing Beyond networks… Strengthening Competitiveness Through Quantum Technology

SEOUL, September 25th, 2023 — LG U+, under the leadership of CEO, Hyeon Sik Hwang, has forged a collaborative alliance with the Korea Advanced Institute of Science and Technology (KAIST) and Qunova Computing to propel the development of a groundbreaking 6G low-earth orbit (LEO) satellite network. This network facilitates seamless connectivity of ground-to-satellite links (SGLs) and inter-satellite-links (ISLs), employing the power of D-Wave’s quantum computing system. The endeavor has resulted in the successful optimization of this intricate network.

This research was carried out as part of an effort to significantly enhance network capabilities using quantum computers, which offer unprecedented processing speeds compared to traditional supercomputers. Through the industry-academic cooperation, LG U+ focused on optimizing end-to-end connections within satellite networks, where high computational power is essential.

The 6G LEO satellite network represents an innovative communication framework, leveraging not just ground stations, but also satellites orbiting within altitudes ranging from 500 to 10,000 km. For effective satellite communication, a robust connection is imperative not only for SGLs, but also for ISLs.

Enabling this connection for GSLs and ISLs mandates real-time adjustments based on a multitude of variables. Unlike stationary geostationary satellites, low-orbit satellites move at speeds of 7.8 km per second, necessitating advanced technology to rapidly determine optimal network configurations. Furthermore, establishing swift communication between low-orbit satellites and ground stations requires the ability to frequently reconfigure the rapid changes of satellite positions.

To establish a competitive edge in satellite network technology, LG U+ embarked on satellite network optimization research in collaboration with a team of KAIST and Qunova Computing led by Professor June-Koo Kevin Rhee, employing the D-Wave™ annealing quantum computer, one of the world’s first commercially accessible quantum systems. This joint effort has yielded remarkable achievement over the last year with the successful establishment of satellite-to-satellite connection optimization and the recent achievement of comprehensive and optimized connectivity, spanning from ground stations to satellites.

In light of this research, LG U+ has demonstrated the 6G satellite networking potential to deliver ultra-performance of user-perceived speeds exceeding 1 Gbps and ultra-precision of end-to-end latency of 5 ms or less in satellite communication environments, rivaling the standards set by terrestrial communication. These attributes align with the traits being developed for 6G communication.

As part of its future initiatives, LG U+ is poised to expand its quantum computing-driven research beyond 6G, exploring avenues to harness quantum characteristics across diverse communication technologies. The findings of this research, including quantum computer-based satellite communication optimization, were unveiled at Quantum Korea 2023, a prominent quantum event held in June.

Sangheon Lee, Leader of Advanced NW Technology Research Unit at LG U+, remarked, " As a part of our ongoing research to harness quantum computing in network technologies, we have successfully optimized end-to-end connections, a pivotal component of 6G satellite communication technology. Our commitment to advancing research in both 6G and quantum communication will further strengthen our network's competitive edge."

Kevin Rhee of KAIST and Qunova Computing has publicly stated, "D-Wave is the only quantum computing technology among existing quantum computers that can demonstrate practical quantum advantage, offering a quantum computing solution well suited for optimization calculations."
