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.

The processor uses qubits that can be measured without error and are resistant to outside interference, which the company says marks a “transformative leap toward practical quantum computing.”

There isn't yet a roadmap to show Microsoft can scale its chip to the million topological qubits required to make a working quantum computer.
