After Google’s Willow comes Microsoft’s Majorana 1, promising more fantastical quantum computing ahead. But does the reality live up to the hype? Satyen K. Bordoloi investigates. So far, we could only say that about AI,

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.
