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.

At least, that's usually my reading of anything quantum computing related, and that seems to be the general gist of Microsoft's new quantum chip announcement. Microsoft says the new chip, the Microsoft Majorana 1,

Microsoft's approach to scalable quantum computer involves the designing qubits using a novel material called topological superconductor.
