The tech giant joins Google and IBM in predicting that a fundamental change in computing technology is much closer than recently believed. Microsoft on Wednesday unveiled a new chip that it said showed quantum computing is “years,

Microsoft is claiming to have created a topological qubit—something engineers have been trying to achieve for years.

Microsoft has long been working on an alternative that could cut down on the overhead by using components that are far more stable. These components, called Majorana quasiparticles, are not real particles. Instead, they are special patterns of behavior that may arise inside certain physical systems and under certain conditions.
