裙状隐变量No-Go定理

Skirting Hidden-Variable No-Go Theorems

A. F. Kracklauer

摘要:

据观察,隐变量不去定理的证明依赖于“投影公设”,这被认为是矛盾的自旋算子在正交于磁场方向的方向。在这一点上,有人认为,这是更便宜的放弃投影公设比放弃局部性,这反过来又使隐藏变量不去定理逃避。为了支持这一点,EPR实验的局部现实主义模型,忽略了投影假设的约束。

英文摘要:

It is observed that the proofs of hidden-variable no-go theorems depend on the `projection postulate,' which is seen to be contradictory with respect to spin operators in directions orthogonal to the magnetic field direction. In this light it is argued that it is less costly to abandon the projection postulate than to abandon locality and this in turn renders Hidden-Variable No-Go Theorems evadible. To buttress this point, a local realist model of the EPR experiment which ignores the constraints of the projection postulate is presented.
