WebJun 18, 2024 · The quantum theory of observation consists in studying the processes of observation with the tools of quantum physics. Both the observed system and the observer system (the measuring apparatus) are considered as quantum systems. The measurement process is determined by their interaction and is described by a unitary evolution operator. WebMar 1, 2024 · Solution 1. A projector is an observable - you can directly check that it is Hermitian $ L\rangle\langle L ^\dagger = L\rangle \langle L $. As to interpretation - a projector onto a single state will measure the value $1$ for definite if the system is in that state. If the system is in an orthogonal state it will measure $0$. gurkhas what are they
