Microsoft's June 2026 demonstration of topological qubit signatures uses nanowire-superconductor hybrids creating Majorana zero modes. Measured coherence: ~1 microsec (vs ~100 microsec for superconducting). Gate fidelity below error-correction threshold. Community concern: all signatures could be explained by topologically trivial Andreev bound states. Verdict: important science, premature engineering.
