Microsoft has introduced Majorana 1, a quantum chip with a "Topological Core" architecture, potentially enabling powerful quantum computers within years instead of decades. The breakthrough stems from a newly developed material called a topoconductor,

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.

Currently, Microsoft has eight – that's how many topological qubits reside on its breakthrough chip. But there's room for scaling to millions. Microsoft has been on this path, now marked with a quantum roadmap, for years. Back in 2017, the Windows giant talked up topological qubits at its Ignite Conference.
