量子态 Quantum state

(重定向自纯态)
Probability densities for the electron of a hydrogen atom in different quantum states.

在量子力学里,量子态英语:quantum state)指的是量子系统的状态。态矢量可以用来抽像地表示量子态。采用狄拉克标记,态矢量表示为右矢|\psi\rangle;其中,在符号内部的希腊字母\psi可以是任何符号,字母,数字,或单字。例如,在计算氢原子能谱时,能级与主量子数n有关,所以,每个量子态的态矢量可以表示为|n \rangle

一般而言,量子态可以是纯态或混合态。上述案例是纯态。混合态是由很多纯态组成的机率混合。不同的组合可能会组成同样的混合态。当量子态是混合态时,可以用密度矩阵做数学描述,这密度矩阵实际给出的是机率,不是密度。纯态也可以用密度矩阵表示。

英语百科

Quantum state 量子态

(重定向自Pure state)
Probability densities for the electron of a hydrogen atom in different quantum states.

In quantum physics, quantum state refers to the state of an isolated quantum system. The quantum state assigns a probability distribution to each observable. Knowledge of the quantum state and the (deterministic) rules for its evolution in time exhausts all that can be predicted about the behavior of the system. A quantum state can be either pure or mixed.
