摘要
A 量子 system's state is identified with a density matrix. Though their probabilistic interpretation is rooted in ensemble theory, density matrices embody a known shortcoming. They do not completely express an ensemble's physical realization. Conveniently, when working only with the 統計 outcomes of projective and positive operator-valued measurements this is not a hindrance. To track ensemble realizations and so remove the shortcoming, we explore geometric 量子 states and explain their physical significance. We emphasize two main consequences: one in 量子 state manipulation and one in 量子 熱力學s.
