Quantum Superposition and Reality: Realities Are Separate But Linked. Quantum physics teaches us that the realiyy we experience is but one wave out of a enormous number of wave possibilities. The wave possibilities is the quantum superposition which contains all the possibilities.
Quantum Superposition-- is a fundamental principle of quantum mechanics. It states that, much like waves in classical physics, any two (or more) quantum states can be added together ("superposed") and the result will be another valid quantum state; and conversely, that every quantum state can be represented as a sum of two or more other distinct states.
