论文摘要
互补性告诉我们，我们不能准确地知道量子对象的所有属性的值同时：一个属性的精确确定意味着其他某些（互补）属性的值是未定义的。例如，对粒子位置的精确知识意味着其动量是不确定的。在这里，我们表明，施罗丁格猫的财产具有明确的价值，该财产与其``死亡或活着''的财产相辅相成。然后，由于互补性，它具有``死亡还是活着''的财产的不确定价值。 换句话说，猫悖论是通过量子互补性来解释的：在其许多互补特性中，任何量子系统（例如猫）都可以一次具有一个良好的定义值。施罗辛格（Schroedinger）的猫具有与``死亡或活着''的属性的确定价值，因此既不死也活着。象征性的人可以说它既死又活着。尽管这种解释仅使用教科书概念（哥本哈根的解释），但显然它从未明确出现在文献中。我们详细介绍了如何基于这些科学外展事件的这些概念来建立基于Arduino的模拟对Schroedinger的实验。
Complementarity tells us we cannot know precisely the values of all the properties of a quantum object at the same time: the precise determination of one property implies that the value of some other (complementary) property is undefined. E.g.the precise knowledge of the position of a particle implies that its momentum is undefined. Here we show that a Schroedinger cat has a well defined value of a property that is complementary to its ``being dead or alive'' property. Then, thanks to complementarity, it has an undefined value of the property ``being dead or alive''. In other words, the cat paradox is explained through quantum complementarity: of its many complementary properties, any quantum system, such as a cat, can have a well defined value only of one at a time. Schroedinger's cat has a definite value of a property which is complementary to ``being dead or alive'', so it is neither dead nor alive. Figuratively one can say it is both dead and alive. While this interpretation only uses textbook concepts (the Copenhagen interpretation), apparently it has never explicitly appeared in the literature. We detail how to build an Arduino based simulation of Schroedinger's experiment based on these concepts for science outreach events.
