This is achieved passively using an adaptive strategy of measurement-no coherent measurements or coherent correction is required. Since the scheme relies on inferring information about what would have been the outcome of a measurement had one been able to carry it out, we call this counterfactual error correction. %Z © 2006 The American Physical Society
