Therefore, its quantum state can be represented as a wave, of arbitrary shape and extending over all of space, called a wavefunction. 因此,其量子態可以表現為波,形狀任意而擴展遍及整個空間,稱作波函數。
In our free particle example, it turns out that it is impossible to find a wavefunction that is an eigenstate of both position and momentum. 我們以自由粒子為例,找到既有位置又有動量的波函數是不可能產生的。
