We theoretically introduce and experimentally demonstrate the realization of a nonclassicality test that allows for arbitrarily low detection efficiency without invoking an extra assumption of independence of the devices. Our test and its implementation is set in a prepare-and-measure scenario with an upper limit on the classical communication capacity of the channel through which the systems are communicated. The essence for our test is the use of two preparation and two measurement devices, which are randomly paired in each round. Our work opens the possibility for experimental realizations of nonclassicality tests with off-the-shelf technology.

非经典性的实验测试，检测效率任意低

我们从理论上介绍并通过实验证明了非经典测试的实现，该测试允许任意降低检测效率而无需调用设备独立性的额外假设。我们的测试及其实现是在准备和测量的场景中进行设置的，该场景对通过系统进行通信的通道的经典通信容量具有上限。我们测试的实质是使用两个准备和两个测量设备，它们在每一轮中随机配对。我们的工作为使用现成技术进行非经典性测试的实验实现开辟了可能性。
