Tech giant Microsoft unveiled a new computer chip on Wednesday that it says could transform everything from fighting pollution to developing new medicines, joining Google and IBM in arguing that the promise of quantum computing is closer to reality.

Its Majorana 1 chip, made of a new material, can perform high-level computing tasks with greater speed and accuracy, Microsoft says.

Majorana 1 relies on ‘topological superconductivity,’ a never-before-seen theoretical form of matter.
