Microsoft is claiming to have created a topological qubit—something engineers have been trying to achieve for years.

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.

Microsoft has made major advances in quantum computing by developing stable, controllable qubits (quantum particles) based on a new topological architecture. These qubits, called Majoranas, exhibit inherent robustness against environmental noise and promise higher speeds,
