Parity of repeated measurements realizes an amplified readout-error channel, enabling drift-resilient, characterization-free mitigation of mid-circuit and terminating measurement and preparation errors.
While the input state is, in general, not known, it is possible to post-select the states that start with'1' in a given qubit and monitor the decay of this subset of states
