The quantum prepare-and-measure scenario has been studied under various physical assumptions on the emitted states. Here, we first discuss how different are conceptually and formally related. We then identify one that can serve as a relaxation of all others, corresponding to limitation one-shot accessible information state ensemble. This motivates us study optimal discrimination probability source subject these assumptions. derive general tight bounds for states restricted by their dimension, vacuum component, an arbitrary uniform overlap, magnitude higher-dimensional signals experimenter's trust in device. Our results constitute step towards more unified picture semi-device-independent processing.
