论文摘要
当两个政党Alice和Bob共享相关的量子系统并执行当地测量结果时，Alice对Bob状态的最新描述可以提供非经典相关性的证据。爱因斯坦，波多尔斯基和罗森（EPR）引入了这种简单的方案，可以通过允许鲍勃还可以将经典或量子系统作为输入来修改。在这种情况下，爱丽丝在鲍勃实验室中更新了她对渠道（而不是国家）的了解。在本文中，我们提供了一个统一的框架，用于研究EPR方案的各种此类概括的非经典性。我们使用一种资源理论这样做，其中免费操作是本地操作和共享随机性（LOSR）。我们得出了一个半决赛计划，用于研究EPR资源的预订，并发现后者之间可能的转换。此外，我们在分析和数值上研究量子后资源之间的转换。
When two parties, Alice and Bob, share correlated quantum systems and Alice performs local measurements, Alice's updated description of Bob's state can provide evidence of nonclassical correlations. This simple scenario, famously introduced by Einstein, Podolsky and Rosen (EPR), can be modified by allowing Bob to also have a classical or quantum system as an input. In this case, Alice updates her knowledge of the channel (rather than of a state) in Bob's lab. In this paper, we provide a unified framework for studying the nonclassicality of various such generalizations of the EPR scenario. We do so using a resource theory wherein the free operations are local operations and shared randomness (LOSR). We derive a semidefinite program for studying the pre-order of EPR resources and discover possible conversions between the latter. Moreover, we study conversions between post-quantum resources both analytically and numerically.
