Unitary contamination, the hidden coherence killer in deep NISQ circuits, pollutes readout. It’s not just qubit decay; it’s ghostly crosstalk.

90% of “mystery quantum noise” vanishes by excluding “orphan” qubits.
Fidelity jump from 0.45 to 0.81 observed. No gate changes.

Forget fault tolerance. On NISQ, measurement hygiene, not gate fidelity, is king. It isolates bad data, unlocking real solutions now.
