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.

Microsoft has outlined its research in a peer-reviewed paper published today in Nature, explaining how its researchers were able to create the topological qubit. Microsoft has helped create a new material made from indium arsenide and aluminum, and it has placed eight topological qubits on a chip that it hopes can eventually scale to 1 million.

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 Corp. announced its first quantum computing chip, a major step in the company’s effort to produce devices that might someday solve problems beyond the reach of modern computers.
