Yes, and everybody in this thread except you understood it in this way. You alone ranted against the name. You want to reserve the name quantum jump for Bohr's old understanding, but others find the term far too descriptive to put it permanently to rest.Sigh. As I said, it's very clear in which sense the notion of "quantum jump" is meant. It's NOT the outdated view a la Bohr within "old quantum mechanics". It's the transition between energy eigenstates of some Hamiltonian due to perturbation.
This non-instantaneous dynamical process is called in modern quantum optics (and already long ago) a quantum jump. (As any jump in real life it takes time, but can often be idealized as being instantaneous.)the spontaneous emission of a photon in that case is not a quantum jump of "old quantum mechanics" but a dynamical process as any other in QED, and for sure it's not instantaneous.
In quantum mechanics (which can be used without invoking QED), the quantum jump is represented by a collapse of the state (another very common term that you decree to be taboo) when a small quantum system passes a filter where it undergoes scattering, or when a single atom is manipulated in an ion trap.
If you would stop fighting for your ideosyncratic restriction of this common terminology in the scientific literature on quantum mechanics, some of the repetitive overhead in the foundational discussions would go away.
