Here is considered a specific detection loophole, that is relevant not only to testing of quantum nonlocality, but also to some other applications of quantum computations and communications. It is described by a simple affine relation between different quantum "data structures" like pure and mixed state, separable and inseparable one. It is shown also, that due to such relations imperfect device for a classical model may mimic measurements of quantum correlations on ideal equipment.
