量子芝诺悖论(Quantum Zeno Paradox)

Perspectives on the quantum Zeno paradox

W. M. Itano

摘要:

截至2006年10月,大约有535次引用了Misra和Sudarshan在1977年的开创性论文,该论文指出了量子芝诺悖论(通常称为量子芝诺效应)。简而言之,量子芝诺效应是指在连续观察到状态的极限下,量子态的演化减慢。关于如何定义量子芝诺效应,以及它是否真的是一个悖论,需要新的物理学,或者仅仅是“普通”量子力学的结果,存在着很大的分歧。Itano,Heinzen,Bollinger和Wineland的实验发表于1990年,被引用了大约347次,似乎是最常被称为量子芝诺效应的演示。既然对于量子芝诺效应是什么存在分歧,那么对于该实验是否证明了量子芝诺效应自然也存在分歧。讨论了关于量子芝诺效应的一些不同观点,以及什么将构成实验演示。

英文摘要:

As of October 2006, there were approximately 535 citations to the seminal 1977 paper of Misra and Sudarshan that pointed out the quantum Zeno paradox (more often called the quantum Zeno effect). In simple terms, the quantum Zeno effect refers to a slowing down of the evolution of a quantum state in the limit that the state is observed continuously. There has been much disagreement as to how the quantum Zeno effect should be defined and as to whether it is really a paradox, requiring new physics, or merely a consequence of "ordinary" quantum mechanics. The experiment of Itano, Heinzen, Bollinger, and Wineland, published in 1990, has been cited around 347 times and seems to be the one most often called a demonstration of the quantum Zeno effect. Given that there is disagreement as to what the quantum Zeno effect is, there naturally is disagreement as to whether that experiment demonstrated the quantum Zeno effect. Some differing perspectives regarding the quantum Zeno effect and what would constitute an experimental demonstration are discussed.
