Phys. Rev. Lett. 97, 120501 (2006) [4 pages]Loss Tolerance in One-Way Quantum Computation via Counterfactual Error CorrectionReceived 18 May 2006; published 20 September 2006 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. © 2006 The American Physical Society URL:
