Quantum computing can power breakthroughs in medicine that would normally take today's systems millions of years to calculate.

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

With its ‘topological’ quantum computers, Microsoft aims to reach useful scales faster than competing technologies

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.
