    "abstract": "The problem of quantum state filtering consists of determining whether an\nunknown quantum state, which is chosen from a known set of states, is either a\nparticular, specified state, or not. We consider this problem for the case that\nthe filtering procedure is required to be unambiguous, which necessitates\nadmitting inconclusive answers when the given states are not orthogonal. As an\napplication, we propose an efficient, probabilistic procedure for\ndistinguishing between sets of Boolean functions, which is an extension of the\nDeutsch-Jozsa algorithm.",
