Microsoft’s new “topological qubit” is not based on a solid, liquid or gas. It is another phase of matter that many experts did not think was possible.

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.

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.”
