In February 2025, Microsoft unveiled a quantum processor built from a new class of materials it calls 'topoconductors,' aiming to eventually scale to a million qubits on a single chip.

Q: What is this Microsoft chip called?

Majorana 1. Majorana 1 uses topological qubits formed from indium arsenide and aluminum nanowires cooled near absolute zero; Microsoft argues this design is inherently more resistant to errors, though some physicists have publicly questioned whether a true topological qubit was demonstrated, and topological qubits aim to protect quantum information using the shape of the physical system itself, rather than relying on many extra error-correcting qubits.

Microsoft's chip is called Majorana 1, built from what the company calls topoconductors, a new class of materials engineered to host topological qubits. The idea is that these qubits protect quantum information using the physical shape and topology of the system itself, rather than relying on large numbers of extra qubits purely for error correction, which Microsoft argues could make scaling toward a million qubits on one chip far more practical.

Azure Quantum One and Topo-1 are not the actual name Microsoft gave this chip, Majorana 1 is the specific name tied to this February 2025 announcement and its topological qubit design.

Not everyone in physics is convinced: some researchers have publicly questioned whether Microsoft's data truly demonstrates a genuine topological qubit, a reminder that even major corporate quantum computing claims still go through rigorous scientific scrutiny before being widely accepted.
