LG U+ and KAIST test quantum computing satellite algorithm
LG U+ and KAIST tested an algorithm to optimize 6G satellite network connections using quantum computing technology, the company said Tuesday.
“The satellite network optimization algorithm is still in its beginning stage,” an LG U+ spokesperson said. “But the research found that it is possible to use the algorithm in enabling ultra-high performance 6G communications with a satellite network in the future.”
Satellite network optimization is a technology to find the shortest path in data transfer using multiple satellites. A network connection using low-earth orbit (LEO) satellites is reconfigured whenever the LEO satellites change their positions in space. Therefore, the network optimization process requires a real-time calculation to find the most effective way to enable network connection between moving satellites.
LG U+ and KAIST solved the calculation problem using D-Wave’s quantum computing system, which is accessible via cloud services. The proposed optimization is more efficient in hop counts between satellites and path length than previously reported studies using previous solutions, according to LG U+.
D-Wave, a Canadian company, is selling the quantum annealing system, the world’s first commercial quantum computer. Quantum computing is capable of solving certain types of problems — especially those involving many variables — much faster than classical computers.
Though the network optimization algorithm still has a long way to go until actual applications, LG U+ explained that the optimization technology will enable a 6G network connectivity in the future, where people have internet access even in the middle of a desert, or during flights.
“We will provide optimized network services by incorporating quantum computer technology,” said Lee Sang-heon, head of the advanced network technology unit at LG U+.
“Collaboration with LG U+ was meaningful as we were able to find an industry application for quantum computing,” said Rhee June-Koo, an engineering professor at KAIST, and CEO of Qunova Computing.
Koo added that “we look forward to more quantum application research on real problems such as in communications, drug and material discovery, logistics, and fintech industries.”
