I've been mildly researching quantum computers to figure out how entanglement and superposition are utilized for higher performance. I understand what these are and I've gotten to the point where it looks like the key is in the logic gate but explanations are vague other than stating that simultaneous possible configurations of all 0s and 1s can be processed at the same time. But what is the actual mechanism involved? I would like a condensed understanding of how the quantum effect is utilized for any particular function. Is this possible or is the explanation too complex for a simple description?
