论文摘要
通过对系统$ a $ b $纠缠的系统$ b $的量子状态的远程测量扰动是否构成了$ b $的真正干扰,即客观更改?仅采用仅出于操作考虑因素而动机的信息理论标准,我们认为所涉及的干扰对于一个可声的相关性是真实的。该结果突出了量子无信号和相对论信号局部性之间的区别。此外,这表明了凸操作理论应该不信号的自然原因:即,确保还原系统的属性与单个系统的属性之间的一致性。
Does the remote measurement-disturbance of the quantum state of a system $B$ by measurement on system $A$ entangled with $B$, constitute a real disturbance -- i.e., an objective alteration -- of $B$ in an operational sense? Employing information theoretic criteria motivated by operational considerations alone, we argue that the disturbance in question is real for a subset of steerable correlations. This result highlights the distinction between quantum no-signaling and relativistic signal-locality. It furthermore suggests a natural reason why a convex operational theory should be non-signaling: namely, to ensure the consistency between the properties of reduced systems and those of single systems.
