一个贝尔不等式,它能比Clauser-Horne不等式更简单地检验局部性,并且比Clauser-Horne-Shimony-Holt不等式的破坏程度更大

A Bell inequality which can be used to test locality more simply than Clauser-Horne inequality and which is violated by a larger magnitude of violation than Clauser-Horne-Shimony-Holt inequality

摘要:

由局部实在论和一个补充假设导出了一个相关不等式。与Clauser-Horne(CH)不等式[或Clauser-Horne-Shimony-Holt(CHSH)不等式]不同,该不等式被量子力学破坏了$\sqrt 2$的因子,该不等式被破坏了1.5的因子。因此,违反这个不等式的幅度大约比违反以前的不等式的幅度大20.7%。此外,与需要测量五个检测概率的CH(或CHSH)不等式不同,本不等式仅需要测量两个检测概率。因此,这个不等式可以比CH或CHSH不等式更简单地用来检验局部性。

英文摘要:

A correlation inequality is derived from local realism and a supplementary assumption. Unlike Clauser-Horne (CH) inequality [or Clauser-Horne-Shimony-Holt (CHSH) inequality] which is violated by quantum mechanics by a factor of $\sqrt 2$, this inequality is violated by a factor of 1.5. Thus the magnitude of violation of this inequality is approximately 20.7% larger than the magnitude of violation of previous inequalities. Moreover, unlike CH (or CHSH) inequality which requires the measurement of five detection probabilities, the present inequality requires the measurement of only two detection probabilities. This inequality can therefore be used to test locality more simply than CH or CHSH inequality.
