摘要
在Bell定理的现有证明中普遍存在着如下两个疑点:(1)认定粒子对中两相关粒子始终处在隐变态空间中的同一点,即始终有相同的隐变数值;(2)认定局域性等价于粒子对中两相关粒子被相应探测器探测到的几率的独立性。此外,某些证明还认定隐变数理论也必须接受诸如测量过程中波包塌缩等量子力学的标准观点。事实上没有任何理由,至少没有给出有力的论证,表明它应当如此。因此Bell定理的现有证明是不可靠的,目前断言所有的隐变数理论已被排除为时尚早.
In the existing proofs of Bell's theorem there exist in common the two doubtful points:(1)Two correlated particles of a pair are considered to be in the same point of the hidden variable space all along,that is,have always equal values of hidden variables;(2)It is holded that the locality is equivalent to the independence of the probabilities that the two correlated particles of a pair are detected by correspondent detectors.Moreover,in some proofs it is maintained that hidden variable theories must accept some standpoints of quantum mechanics,such as wave-parket collapoe in a measurement progress and so on. In fact, there is not any reason,at least no forcible argue-ment is given, why it should be so.Hence,the existing proofs of Bell's theorem are unreliable,and it is too early now to clai m that the local hidden variable theories have been ruled out.
