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.
我们介绍了一种在簇态计算中容错处理损耗（或其他“泄漏”错误）的方案，该方案可容忍高达50%的量子比特损耗。这是通过使用一种自适应测量策略被动实现的——无需相干测量或相干校正。由于该方案依赖于推断如果能够进行测量将会得到的测量结果的信息，我们将其称为反事实错误校正。
