This solved it for me too , much thanks on Thanksgiving . <| sep |> Requires a smaller crew to efficiently operateFalse Likely far lower operational costsOutweighed by higher profits Might have access to a different class of jump points ? Have a look at the starmap and count the little jump points . <| sep |> Your being fairly loose with terminology here , you don ' t ' collapse the hilbert space '. And the space isn ' t spanned by the wave function , it ' s an element of it . The eigenfunctions of any hermitian operator observable on the space span the space eigenbasis . The pauli matrices and the complex 2 d space is an easy example of this . This means you can write your wave function as an expansion in this basis . When you preform a measurement your wavefunction collapses into an eigenfunction of the measurement operator with a probability related to the coefficient in the expansion the overlap of the wavefunction and the eigenfunction . So your wavefunction is now an eigenfunction of your operator . This eigenfunction can then be written as an expansion of another operator ' s eigenbasis i . e an eigenfunction of one operator is a superposition of the eigenfunctions of another operator if they don ' t commute . I am pretty sure operators never share single eigenfunctions , its either all or none . You can reask the other questions as they are currently based on misconceptions which hopefully this corrects .
