Microsoft on Wednesday unveiled a new chip that it said showed quantum computing is "years, not decades" away, joining Google and IBM in predicting that a fundamental change in computing technology is much closer than recently believed.

Microsoft on Wednesday debuted its Mojarana 1 quantum computing chip. The news comes just two months after Google announced its own quantum chip.

Microsoft unveiled the Majorana 1 quantum chip, claiming useful quantum computing is "years, not decades" away. Using Majorana fermions, it aims to reduce errors, competing with Google and IBM in the race for scalable quantum systems.

Microsoft says it has developed a breakthrough quantum processor based on a new state of matter, giving it a clear path to achieve quantum computing’s long-term promise of solving some of the world’s most difficult problems.
