我们计算了Mermin的n粒子贝尔不等式中的信噪比[物理学]。[Rev. Lett. 65, 1838(1990)]基于源噪声、数据误差和统计不确定性。我们发现，只要每个探测器或每个粒子的噪声小于约14%，违例信号的指数增长速度就比指数增长的噪声快。或者，在没有噪声的情况下，检测器效率低至71%，可以进行无漏洞测试
We calculate the signal-to-noise ratio in Mermin's n-particle Bell inequality [Phys. Rev. Lett. 65, 1838 (1990)] based on source noise, data error, and statistical uncertainty. We find that the signal for violation grows exponentially faster than the exponentially growing noise, as long as the noise per detector or per particle is less than about 14%. Alternately, in the absence of noise a loophole-free test could be made with detector efficiencies as low as 71%
