Idea

The Born rule is the core statement of coordination in the foundations of quantum physics:

In its version for pure states the Born rule says that

then the probability of observing the given eigenstate in a quantum system which is in state ψ\psi equals

ψ|P|ψψ|ψ \frac{ \langle \psi \vert P \vert \psi \rangle }{ \langle \psi \vert \psi \rangle }
