Microsoft has shared an update on its Majorana 1 quantum computer, which uses a topological qubit for speed, compactness, reliability, and controllability. The company aims to scale this technology for large qubit quantities, potentially ushering in an age of quantum computing.

Majorana 1 is named after Ettore Majorana, who theorized particles that are their own antiparticles. Microsoft's qubit focuses on harnessing this property. While not yet at a million qubit supercomputer, Majorana 1 is a significant step towards that goal.

The challenge now is the speed of scaling. If Microsoft can scale to one million qubits quickly, it could lead to practical quantum computing. Otherwise, it may be another decade before we see the promise of quantum computing realized.
