With its ‘topological’ quantum computers, Microsoft aims to reach useful scales faster than competing technologies

After many years of work, Microsoft has unveiled its first quantum hardware, the Majorana 1 processor. Let’s grok its topoconductor and tetron-based qubits.

The company said it created a “new state of matter” that represents a major advance for quantum computing. But physicists who have reviewed the work say they aren’t convinced of the finding.
