👉 Pleinipotentiality, in physics and quantum mechanics, refers to a property of a quantum system that allows it to be simultaneously in multiple states at once. It is often used in conjunction with the concept of superposition, where a state can exist as a wave or a particle, but not both at the same time. In classical mechanics, plenipotentiality implies that a system is capable of having two different states simultaneously. In quantum mechanics, it describes the ability to simultaneously
