As each quantum bit contains two probability amplitudes, each particle occupies two positions in space.Hence, the process of searching is accelerated. 因每個(gè)量子位有兩個(gè)概率幅，故每個(gè)粒子同時(shí)占據空間兩個(gè)位置，在粒子數目相同時(shí)，能加速粒子的搜索進(jìn)程。
Any alternative of quantum mechanics must be able to explain two-slit experiments, therefore it must contain passage conditions or probability amplitudes. 任何替代量子力學(xué)解釋量子現象的理論都得說(shuō)明雙縫衍射實(shí)驗，這就必須引進(jìn)通道條件或引進(jìn)概率幅。
Whereas the absolute value of the probability amplitude encodes information about probabilities, its phase encodes information about the interference between quantum states. 但是概率振幅的絕對值編碼了概率信息，其相位編碼了量子態(tài)之間的干涉。
