Qiskit explains how parity checks, stabilizer measurements and combinations of checks can flag suspect quantum-computing runs so they can be discarded. The lesson introduces post-selection, with useful context for understanding error-correction research. The important trade-off is that rejecting runs reduces the number of usable samples; this is an error-detection approach, not a demonstration of full fault-tolerant computation or quantum advantage.
