When we collapse a wave function, say a photon into it's single particular form, are we inputting energy into a system? Is it an overall endothermic reaction i.e. is the photon more or less energetic after the collapse-do we even know this? Are we not closing it's possible locations and are we not reversing the arrow of disordered states ? Great help much appreciated very confused kid here.
