TY - JOUR AV - public VL - 97 Y1 - 2006/09/22/ TI - Loss tolerance in one-way quantum computation via counterfactual error correction IS - 12 N1 - © 2006 The American Physical Society PB - AMERICAN PHYSICAL SOC UR - http://dx.doi.org/10.1103/PhysRevLett.97.120501 SN - 0031-9007 N2 - We introduce a scheme for fault tolerantly dealing with losses (or other "leakage" errors) in cluster state computation that can tolerate up to 50% qubit loss. 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.
