{"slug":"topological-superconductivity","topic":"topological-superconductivity","title":"Topological Superconductivity & Majorana Modes: State of the Field (October 2026)","summary":"This briefing reviews Majorana zero modes and topological superconductivity as of late October 2026, covering semiconductor-superconductor nanowires, quantum-dot Kitaev chains, vortex and magnetic-atom platforms, and the Majorana parity-qubit program. Its central takeaway is that zero-bias peaks alone do not establish a topological phase, that the protocol used to certify hybrid devices is disputed, and that the newest qubit results are preprints awaiting independent replication.","version":1,"published_at":"2026-10-30","updated_at":"2026-10-30","stats":{"words":3427,"citations":44,"claims":29,"timeline":20,"benchmarks":8,"open_problems":6,"key_papers":15,"glossary":15},"verification":{"status":"verified","method":"automated figure and citation-relevance triage against cited abstracts, plus targeted AI review with web checks of flagged statements; automated citation resolution","claims_checked":6,"issues_fixed":3,"verified_at":"2026-10-30"},"ai_assisted":true,"price":{"usd":"0.20","protocol":"x402","network":"eip155:84532","asset":"USDC"},"url":"https://space-kitty.com/dossiers/topological-superconductivity","preview_url":"https://space-kitty.com/api/v1/dossiers/topological-superconductivity/preview","purchase_url":"https://space-kitty.com/api/v1/dossiers/topological-superconductivity","toc":[{"level":2,"text":"Executive summary","anchor":"executive-summary"},{"level":2,"text":"Background and core concepts","anchor":"background-and-core-concepts"},{"level":2,"text":"Timeline of key milestones","anchor":"timeline-of-key-milestones"},{"level":2,"text":"State of the art","anchor":"state-of-the-art"},{"level":3,"text":"Nanowires and zero-bias peaks","anchor":"nanowires-and-zero-bias-peaks"},{"level":3,"text":"Quantum-dot Kitaev chains","anchor":"quantum-dot-kitaev-chains"},{"level":3,"text":"Parity readout and tetron devices","anchor":"parity-readout-and-tetron-devices"},{"level":3,"text":"Majorana parity qubit in minimal Kitaev chains","anchor":"majorana-parity-qubit-in-minimal-kitaev-chains"},{"level":3,"text":"Vortex and magnetic-atom platforms","anchor":"vortex-and-magnetic-atom-platforms"},{"level":3,"text":"Quantitative benchmarks","anchor":"quantitative-benchmarks"},{"level":2,"text":"Open problems and active debates","anchor":"open-problems-and-active-debates"},{"level":2,"text":"Major programs and players","anchor":"major-programs-and-players"},{"level":2,"text":"Outlook: what to watch (near term)","anchor":"outlook-what-to-watch-near-term"},{"level":2,"text":"Key papers","anchor":"key-papers"},{"level":2,"text":"Glossary","anchor":"glossary"}],"sample_claims":["Partially separated Andreev bound states can produce conductance plateaus near 2e²/h over broad parameter ranges without Majorana zero modes.","Majorana-like resonances, including zero-bias pinning, become common in InSb nanowire devices at finite magnetic field."],"includes":["markdown","claims","timeline","benchmarks","open_problems","key_papers","glossary","bibliography"],"citation_count":44,"how_to_buy":"GET https://space-kitty.com/api/v1/dossiers/topological-superconductivity with an x402 client ($0.20, USDC on Base Sepolia (testnet))."}
