量子力学的一个基本预测是，可观测量可以通过理想测量来测量，即重复时给出相同结果且不干扰任何可联合测量的可观测量的测量。就量子仪器而言，这种理想测量由投影效应连同相关的吕德斯态更新规则来描述。在这里，我们表明量子力学允许自检验任何理想测量。仅利用有时添加非破坏性测量的双部贝尔测试的输出统计，就可以以设备无关的方式认证所添加的测量是否为理想的。
英文摘要
A fundamental prediction of quantum mechanics is that observables can be measured through ideal measurements, that is, measurements that give the same outcome when repeated and do not disturb any observable that is jointly measurable. In terms of quantum instruments, such an ideal measurement is described by projective effects together with the associated Luders state-update rule. Here, we show that quantum mechanics allows for self-testing any ideal measurement. Using solely the output statistics of bipartite Bell tests in which a non-demolition measurement is sometimes added, it is possible to certify in a device-independent manner whether the added measurement is ideal.
