论文摘要
近来，量子状态无关的量子认证已成为量子信息中深入研究的领域之一。但是，所有这些方案都利用几乎难以生成的投射测量值。在这项工作中，我们考虑了独立于设备的（1SDI）方案，并为两分点纠缠的状态提出了一种自我测试方案，尤其是三个三结果极端POVM。我们还分析了计划对白噪声的鲁棒性。
In recent times, device-independent certification of quantum states has been one of the intensively studied areas in quantum information. However, all such schemes utilise projective measurements which are practically difficult to generate. In this work, we consider the one-sided device-independent (1SDI) scenario, and propose a self-testing scheme for the two-qubit maximally entangled state using non-projective measurements, in particular, three three-outcome extremal POVM's. We also analyse the robustness of our scheme against white noise.
