Bell定理与空间局部性

Bell's Theorem and Locality in Space

Igor V. Volovich

摘要:

贝尔定理指出,某些量子关联不能用分离随机变量的经典关联来表示。它被解释为局域性要求与量子力学不相容。指出在贝尔定理的证明中,实际上忽略了波函数的空间部分。然而,这一空间部分对于考虑量子系统的定域性是至关重要的。实际上,空间部分导致了量子关联中的一个额外因素,结果贝尔定理的普通证明在这种情况下失败了。本文提出了隐变量实在论中的局部性准则。证明了量子力学对高斯波函数的预言与贝尔不等式是一致的,从而恢复了爱因斯坦的局域实在论。

英文摘要:

Bell's theorem states that some quantum correlations can not be represented by classical correlations of separated random variables. It has been interpreted as incompatibility of the requirement of locality with quantum mechanics. We point out that in fact the space part of the wave function was neglected in the proof of Bell's theorem. However this space part is crucial for considerations of property of locality of quantum system. Actually the space part leads to an extra factor in quantum correlations and as a result the ordinary proof of Bell's theorem fails in this case. We present a criterium of locality in a realist theory of hidden variables. It is argued that predictions of quantum mechanics for Gaussian wave functions can be consistent with Bell's inequalities and hence Einstein's local realism is restored in this case.
