Episode 24 zooms in on a near-term engineering compromise the industry isn't shouting about: the first fault-tolerant quantum computers will likely be single-purpose machines optimized for one algorithm — not general-purpose devices. Lucas explains why ion-trap and neutral-atom architectures are racing to demonstrate a 'logical qubit' with error correction on a specific chemistry or optimization problem by 2028, while superconducting qubits chase gate counts. Luna pushes back on whether this reduces quantum to a glorified ASIC. The episode names concrete timelines from Quantinuum and Atom Computing, cites the 2025 Nature paper showing 48 logical qubits in a single trap, and walks through the business bet: if the first useful machine can only do one thing, the winner is whichever vendor picks the right problem.
