Microsoft Unveils First Quantum Processor With Topological Qubits

The development follows Microsoft’s earlier breakthrough: the creation of a topoconductor, a material engineered to exhibit topological superconductivity — a state of matter that previously existed only in theory. Microsoft’s research team combined indium arsenide (a semiconductor) with aluminum (a superconductor) to fabricate gate-defined devices that, when cooled to near absolute zero, form nanowires with MZMs at their ends. These MZMs provide an intrinsic layer of protection against quantum decoherence, a fundamental challenge in quantum computing.
