    "abstract": "Two measures of fidelity are proposed for postselecting devices, the\nretrodictive conditional probability that the state in the measurement arm is\nthe one indicated by the detectors, and the probability that the device\nproduces the state that it would produce if working perfectly. The first is the\nnatural quantity that one wishes to maximise to improve the device operation.\nThe second corresponds more closely with the accurate operation of the device\nthan the more usual overlap-based fidelity. The results are particularly\napplicable to the types of state preparation and logic gate operation in linear\noptical quantum computing.",
