Perturbation theory is one important part of quantum physics since it allows to calculate corrections of systems which would be harder or even impossible using the explicit calculations.

Quantum superposition, one of the most important results of quantum physics that states that an object can be in more than one state at the same time, and some even interpret it as the existence of parallel universes.

One of the coolest features of quantum mechanics that classical physics couldn't explain, the great tunneling effect.

Quantum entanglement. Conceptual artwork of a pair of entangled quantum particles or events (left and right) interacting at a distance. Quantum entanglement is one of the consequences of quantum theory. Two particles will appear to be linked across space and time, with changes to one of the particles (such as an observation or measurement) affecting the other one. This instantaneous effect appears to be independent of both space and time, meaning that, in the quantum realm, effect may precede cause.
