Characterizing Quantum Properties of a Measurement Apparatus: Insights from the Retrodictive Approach
Using the retrodictive approach of quantum physics, we show that the state retrodicted from the response of a measurement apparatus is a convenient tool to fully characterize its quantum properties. We translate in terms of this state some interesting aspects of the quantum behavior of a detector, such as the …
