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.

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 announced Majorana 1, its first quantum computing chip. The achievement comes after the company has spent nearly two decades of research in the field.
