One can even set up quite ridiculous cases. A cat is penned up in a steel chamber, along with the following device (which must be secured against direct interference by the cat): in a Geiger counter, there is a tiny bit of radioactive substance, so small, that perhaps in the course of the hour one of the atoms decays, but also, with equal probability, perhaps none; if it happens, the counter tube discharges and through a relay releases a hammer that shatters a small flask of hydrocyanic acid. If one has left this entire system to itself for an hour, one would say that the cat still lives if meanwhile no atom has decayed. The first atomic decay would have poisoned it. The psi-function of the entire system would express this by having in it the living and dead cat (pardon the expression) mixed or smeared out in equal parts.

It is typical of these cases that an indeterminacy originally restricted to the atomic domain becomes transformed into macroscopic indeterminacy, which can then be resolved by direct observation. That prevents us from so naïvely accepting as valid a "blurred model" for representing reality. In itself, it would not embody anything unclear or contradictory.

在这些情况下，典型的情况是，最初局限于原子域的不确定性转变为宏观不确定性，这种不确定性可以通过直接观察得到解决。这使我们无法轻易地接受代表现实的“模糊模型”作为有效的模型。它本身不会包含任何不清楚或矛盾的东西。'''<font color="#32CD32">摇晃的失焦的照片与云层和雾层的快照是有区别的。</font>'''

Schrödinger's famous [[thought experiment]] poses the question, "''when'' does a quantum system stop existing as a superposition of states and become one or the other?" (More technically, when does the actual quantum state stop being a non-trivial [[linear combination]] of states, each of which resembles different classical states, and instead begin to have a unique classical description?) If the cat survives, it remembers only being alive. But explanations of the EPR experiments that are consistent with standard microscopic quantum mechanics require that macroscopic objects, such as cats and notebooks, do not always have unique classical descriptions. The thought experiment illustrates this apparent paradox. Our intuition says that no observer can be in a mixture of states—yet the cat, it seems from the thought experiment, can be such a mixture. Is the cat required to be an observer, or does its existence in a single well-defined classical state require another external observer? Each alternative seemed absurd to Einstein, who was impressed by the ability of the thought experiment to highlight these issues. In a letter to Schrödinger dated 1950, he wrote:

除了劳厄之外，您是唯一的当代物理学家，他发现只有诚实的人才能绕开对现实的假设。他们中的大多数人根本不知道他们在玩什么样的冒险游戏-现实是独立于实验建立的东西。但是，你的系统——放射性原子+放大器+火药电荷+盒子里的猫优雅地驳斥了他们的解释，在这个系统里，psi功能既包含活的猫，也包含被炸成碎片的猫。没有人真的怀疑猫的存在或不存在与观察行为无关。<br>

量子力学的主流诠释之一是哥本哈根诠释。该诠释认为，一个系统在观察时将不再处于叠加态，而是坍缩为叠加态中的任意一种状态。薛定谔的思维实验清楚地表明，哥本哈根诠释没有明确定义测量和观察的本质。实验可以解释为，盒子关闭时，系统处于“衰变的原子核/死猫”和“未衰变的原子核/活猫”叠加态中，只有打开盒子进行观察时，波函数才会坍缩成这两种状态之一。

但是，哥本哈根诠释的主要科学家尼尔斯·玻尔从未认为是观察者引起了波函数的坍缩，因为他并不认为波函数真实存在，它只是一个统计工具。因此薛定谔的猫对他来说不是什么谜题。早在意识的观察者打开盒子前，猫就已经死去或者仍然活着。分析一个真实的实验会发现，尽管实验涉及的有效性尚有争议，在有意识的观察者对测量结果进行观察前，测量本身（比如盖革计数器）就足以使量子波函数发生坍缩。（这种当原子核中的粒子撞击监测器时“观察”已经发生的观点可以发展为客观坍缩理论。在薛定谔的思维实验中，波函数要发生坍缩，监测器需要进行“无意识观察”。相比之下，“多世界理论”否认曾发生过坍缩。

1957年，休·埃弗莱特提出了量子力学的多世界诠释，该诠释并不把观察视为一个特殊过程。在多世界诠释中，盒子打开后，活猫和死猫仍然存在，但彼此之间是退相干的。换句话说，盒子被打开时，观察者和可能死亡的猫分裂成两个分支：观察者看着盒中的死猫，观察者看着盒中的活猫。但由于死态和活态是退相干的，它们之间无法发生有效的交流或相互作用。

薛定谔的猫实验是纯理论性的，所涉及的实验装置并被制造出来。但是，很多涉及类似原理的实验已经取得成功，例如一些（在量子力学标准中）相对较大系统的叠加态已经实现。这些实验并没有表明与猫大小一样的物体可以处于叠加态，但是这些实验提升了存在“猫态”的系统的大小上线。在很多实验中，即使冷却到接近绝对零度，猫态也只能短暂存在。
