<human>:  What are the basic principles of quantum mechanics?
<bot>: The basic principles of quantum mechanics are that energy is quantized and found in discrete packets called quanta; particles like electrons exist in a wave-like state; the Heisenberg Uncertainty Principle, which states that it is impossible to know both the exact position and momentum of a particle; the Pauli Exclusion Principle, which states that two electrons in the same quantum state cannot occupy the same position; and that particles can exist in multiple states simultaneously.
