Isn't the dot product already the squared magnitude?pic.twitter.com/1briCwprrz
I think the dot product just projects onto the measurement basis. For standard basis, phi is a one-hot vector and the dot product just selects an entry of psi. The entry times its complex conjugate is the probability of measuring phi, as opposed to a different one-hot vector.
there’s a lot of non-Standard terminology there..
There is no probability of measuring phi.. only its eigenvalue
Every different technical field invents different nomenclature for what are essentially the same concepts. 'Non-standard terminology' assumes a preferred frame of reference! :D Brb, googling 'one-hot'.
Haha, yeah I mean a vector of the standard basis where one element is 1 and all others are 0. Does it make sense to measure in the standard basis if we can only measure eigenvalues though?
I guess I’m just not sure what you mean by measure in the standard basis .. the measurement is a physical process and is basis independent and is represented by a unitary operator acting on the projective Hilbert space
Terminology 
Side effect of CS foundation is thinking in terms of data structures used to represent concepts in memory. In practice this means vectors always need a basis. In this case, a dot product can become a fast lookup if 𝜓 is represented using the operator's eigenvectors as a basis.
Can we make these vectors independent of basis? So that we can define any basis space whenever we want for these vectors in order to get output accordingly! These basis space may be a data structure, these vectors then gives components based on what data structure we impose!
