Do quantum error-correcting codes finally break even on a real machine?

Encoding 4 logical qubits into 18 physical ones, a trapped-ion processor achieved logical error rates 9× better than comparable superconducting experiments — and in some cases the protected qubit lasted as long as the unprotected hardware itself, the 'breakeven' milestone. The same device ran nine fundamentally different error-correcting codes without any hardware changes, sidestepping the long-range wiring that makes these codes hard to build on chips. That flexibility, plus a cleaner mid-circuit measurement technique that cuts ion-shuffling overhead, suggests trapped-ion systems may have a structural edge in the near-term race toward fault-tolerant quantum computing.
