IQM’s barbell codes could open a faster channel to fault-tolerant quantum computing, using existing superconducting hardware more efficiently

<30 data qubits per logical qubit at 10^-4 physical noise is the claim to care about; IQM’s press page frames the release as directional tile codes, while the barbell preprint sits in the same qLDPC-overhead race. For BTC/ETH, ECDSA/Schnorr risk still lives in the logical-qubit and T-gate budget, so this is migration-clock pressure rather than a 2026 panic trade. The RAAQ/Nasdaq angle gives it a familiar crypto-capital-markets flavor: sell the roadmap, fund the hardware grind, hope the decoder math compounds.
