Ericsson Pioneers Quantum Computing Research with Eye on Future Telecom Breakthroughs

Ericsson has been intensively exploring quantum computing for over a decade, guided by research chief Catrin Granbom, who has over 30 years of experience in telecommunications and computer science. Since 2016-2017, Ericsson’s efforts have centered on understanding how quantum technology could complement classical computing rather than replace it, especially in handling complex problems that traditional computers cannot efficiently solve.

Granbom emphasizes that quantum computers act as accelerators for specific calculations, with key applications potentially emerging in network optimization, automation, artificial intelligence, and machine learning. One promising use case includes optimizing antenna tilt through quantum calculations to enhance network performance.

Despite quantum computers still being in a developmental phase—with full-scale functional machines yet to be realized—Ericsson actively simulates their potential and participates in national research programs utilizing IBM’s quantum computers. The company's vision also extends beyond computing to include quantum sensors and synchronization technologies, which could offer additional advances.

Annually, Ericsson invests about 50 billion SEK in research and development, fostering collaborations with universities and countries like Canada and Hungary to propel Sweden’s position in quantum technology. Granbom notes the rapid progress of quantum initiatives in countries such as England but stresses that major breakthroughs may not happen until after 2030. Nonetheless, Ericsson prepares proactively for accelerated development, drawing parallels with the swift emergence of AI innovations like ChatGPT.

This strategic approach aligns with Ericsson’s broader commitment to leading the next technological shift in telecommunications, ensuring Sweden remains competitive in the evolving quantum landscape.
