论纠缠在薛定谔猫悖论中的作用

On the Role of Entanglement in Schroedinger's Cat Paradox

S. Rinner, E. Werner

摘要:

本文对薛定谔的“猫悖论”的核心进行了重新研究。我们认为,人们必须明确区分宏观猫态的叠加和纠缠态的叠加,其中包括猫的状态。它示出,在第一个实例中复发退相干或其他机制是没有必要的,在这种特殊情况下,以解释宏观叠加的情况。此外,我们提出了两个量子光学实验的修改版本作为experimenta crucis。严格地应用,量子力学形式主义将问题简化为一个纯粹的伪悖论。

英文摘要:

In this paper we re-investigate the core of Schroedinger's 'cat paradox'. We argue that one has to distinguish clearly between superpositions of macroscopic cat states and superpositions of entangled states which comprise both the state of the cat. It is shown, that in the first instance recurrence to decoherence or other mechanisms is not necessary in this special case in order to explain the absence of macroscopic superpositions. Additionally, we present modified versions of two quantum optical experiments as experimenta crucis. Applied rigorously, quantum mechanical formalism reduces the problem to a mere pseudo-paradox.
