👉 The term "coinitial" in quantum mechanics refers to a state that is simultaneously an initial and final state. This concept is used in quantum information theory, where it describes a system or process that evolves from one state (the initial state) to another state (the final state), without leaving the intermediate state between them. In simple terms, "coinitial" means that the system is in a state that has not yet reached its final state. This state could be an initial state such as the
