Microsoft announced the creation of Majorana 1, a quantum processor using topological qubits. 

This processor aims to scale to one million qubits using a novel material called a topoconductor.

A related research paper details the creation and measurement of fermion parity in indium arsenide-aluminum heterostructures, using an interferometric technique with quantum dots coupled to a nanowire, achieving a single-shot measurement with a 1% error probability. 

This parity measurement is a crucial element for measurement-based topological quantum computing. 

The technology achieves reliable quantum computation through simplified quantum error correction using digital pulses. 

These advancements mark significant progress in building a fault-tolerant quantum computer, with DARPA recognizing Microsoft's approach
