论文摘要
非本地性质在于局部测量之间存在非古典相关性。到目前为止，它主要在孤立的量子系统中进行了研究。在这里，我们表明存在非本地相关性，可以检测到，并且在稳态和瞬态方案中的多体开放量子系统中也可能对噪声也有鲁棒性。当开放量子系统经过重复测量时，我们进一步讨论了非本地相关性的鲁棒性，这是量子加密的相关情况。
Non-locality consists in the existence of non-classical correlations between local measurements. So far, it has been investigated mostly in isolated quantum systems. Here we show that non-local correlations are present, can be detected and might be robust against noise also in many-body open quantum systems, both in the steady-state and in the transient regime. We further discuss the robustness of non-local correlations when the open quantum system undergoes repeated measurements, a relevant scenario for quantum cryptography.
