Microsoft announced the world's first topological qubit in February 2025, based on Majorana zero modes in semiconductor-superconductor nanowires. Topological qubits store information non-locally, making them inherently resistant to local noise. If scaled, this approach could dramatically reduce the overhead needed for error correction. Microsoft aims for a million-qubit topological quantum computer.
