Quantum error correction goes well beyond breakeven

Ars Technica reports: Running complicated algorithms on quantum computing hardware is going to require the use of logical qubits, where collections of hardware qubits are linked together in ways that allow errors to be detected and corrected.
In general, the more hardware qubits you dedicate to each logical qubit, the better the chances are of identifying errors. If the hardware error rate is too high, then growing the logical qubit will only make matters worse.…
