Interpretations of Quantum Mechanics: a critical - Philsci
... Historically, the understanding of the mathematical structure of QM went trough various stages. Very briefly, the Copenhagen interpretation assumes two processes influencing the wavefunction, namely, i) its unitary evolution according to the Schrödinger equation, and ii) the process of measurement. ...

... The state of two spinors is prepared such that the z-component of the spin is zero. If we measure m = +1/2 for one particle, then the other particle must have m =-1/2. The measurement performed on one particle resulted in the collapse of the wavefunction of the other particle. ...

Generally speaking, the compatibility of QM with physical realism has been much debated in the literature [10–19], giving rise to many different interpretations of QM [20]. ...
