Measurements are one of the main ingredients in physics. The description of a particular measurement depends on a variety of factors. First, one has a measurement device, which is assumed to perform a measurement of some physical observable. Second, based on the knowledge what observable one wants to measure, a theoretical model for the device is constructed. This theoretical model is believed to describe the processing of the device faithfully. In this talk we address the question of device modeling and its application to the quantum key distribution (QKD) protocols.
