Two weeks ago, Microsoft made a big splash in the media by claiming that they’d found a way to build a scalable quantum computing platform which could reach one million qubits in a short period of time. They claimed this was possible with the help of a type of topological qubit called Majorana states. But it appears there are several… issues with the company’s published research. I have a quick summary.
