评J.H.“贝尔不等式与量子力学“Eberly

Comment on "Bell inequalities and quantum mechanics" by J. H. Eberly

Luiz Carlos Ryff

摘要:

指出了Eberly在推导几个贝尔不等式时的错误:(1)它是基于一个不正确的方程;(2)它既没有利用两粒子态也没有利用定域性来推导贝尔不等式;(3)它没有利用纠缠来获得贝尔不等式的违反。即使是领先的和杰出的物理学家-当然是埃伯利教授的情况-有时会犯基本的错误,这绝不会削弱他们的科学贡献的重要性。总的来说,这是过分依附于一种观念的结果(现在反对现实主义已经成为一种时尚)。这表明了保持开放心态的重要性。

英文摘要:

Errors in Eberly's derivation of several Bell inequalities are pointed out: (1) it is based on an equation that is incorrect; (2) it uses neither two-particle states nor locality to derive Bell's inequalities and; (3) it does not use entanglement to obtain violations of Bell's inequalities. Even leading and outstanding physicists -- as certainly is the case of Prof. Eberly -- sometimes make elementary mistakes, and this by no means diminishes the importance of their scientific contribution. In general, this is a consequence of an excessive attachment to an idea (nowadays it has become fashionable to be against realism). This shows the importance of trying to keep an open mind.
